-<h1 id="caching">Caching</h1>
-<p>Caching is used to speed up a call to <a href="../api-functions/api-display/"><code>display()</code></a> or
-<a href="../api-functions/api-fetch/"><code>fetch()</code></a> by saving its output to a file. If a cached
-version of the call is available, that is displayed instead of
-regenerating the output. Caching can speed things up tremendously,
-especially templates with longer computation times. Since the output of
-<a href="../api-functions/api-display/"><code>display()</code></a> or <a href="../api-functions/api-fetch/"><code>fetch()</code></a> is cached, one
-cache file could conceivably be made up of several template files,
-config files, etc.</p>
-<p>Since templates are dynamic, it is important to be careful what you are
-caching and for how long. For instance, if you are displaying the front
-page of your website that does not change its content very often, it
-might work well to cache this page for an hour or more. On the other
-hand, if you are displaying a page with a timetable containing new
-information by the minute, it would not make sense to cache this page.</p>

+</code></pre></div>
+<p>Say you have a template file called 'version.tpl', stored in the 'templates' directory like this:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-3-1" name="__codelineno-3-1" href="#__codelineno-3-1"></a><span class="x">&lt;h1&gt;Hi&lt;/h1&gt;</span>

+<p>You can now render this, using:

+</code></pre></div></p>
+<h2 id="assigning-variables">Assigning variables</h2>
+<p>Templates start to become really useful once you add variables to the mix.</p>
+<p>Create a template called 'footer.tpl' in the 'templates' directory like this:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-5-1" name="__codelineno-5-1" href="#__codelineno-5-1"></a><span class="x">&lt;small&gt;Copyright </span><span class="cp">{</span><span class="nv">$companyName</span><span class="o">|</span><span class="na">escape</span><span class="cp">}</span><span class="x">&lt;/small&gt;</span>
+</code></pre></div></p>
+<p>Now assign a value to the 'companyName' variable and render your template like this:</p>
+<div class="highlight"><pre><span></span><code><a id="__codelineno-6-1" name="__codelineno-6-1" href="#__codelineno-6-1"></a><span class="cp">&lt;?php</span>

+<h1 id="caching">Caching</h1>
+<p>Caching is used to speed up the rendering of a template by saving and re-using the output. </p>
+<p>If a cached version of the call is available, that is displayed instead of
+regenerating the output. Caching can speed things up tremendously,
+especially templates with longer computation times. </p>
+<p>Since templates can include or extend other templates, one
+cache file could conceivably be made up of several template files,
+config files, etc.</p>
+<blockquote>
+<p><strong> Note </strong></p>
+<p>Since templates are dynamic, it is important to be careful what you are
+caching and for how long. For instance, if you are displaying the front
+page of your website that does not change its content very often, it
+might work well to cache this page for an hour or more. On the other
+hand, if you are displaying a page with a timetable containing new
+information by the minute, it would not make sense to cache this page.</p>
+</blockquote>
+<h2 id="setting-up-caching">Setting Up Caching</h2>
+<p>The first thing to do is enable caching by calling <code>Smarty::setCaching()</code> with either
+<code>\Smarty\Smarty::CACHING_LIFETIME_CURRENT</code> or <code>\Smarty\Smarty::CACHING_LIFETIME_SAVED</code>.
+Or with <code>\Smarty\Smarty::CACHING_OFF</code> to disable caching again.</p>

+</code></pre></div>
+<p>With caching enabled, the function call to <code>$smarty-&gt;display('index.tpl')</code> will
+render the template as usual, but also saves a copy of its output. On the
+next call to <code>$smarty-&gt;display('index.tpl')</code>, the cached copy will be used
+instead of rendering the template again.</p>
+<blockquote>
+<p><strong>Note</strong></p>
+<p>By default, Smarty saved its caches as files in a dir called <code>cache</code> relative to the current 
+directory. The default directory can be changed using <code>$smarty-&gt;setCacheDir('/some/cache/dir');</code> 
+The files are named similar
+to the template name. Although they end in the <code>.php</code> extension, they
+are not intended to be directly executable. Do not edit these files!</p>
+</blockquote>
+<h2 id="cache-lifetime">Cache lifetime</h2>
+<p>Each cached page has a limited lifetime. The default value is 3600
+seconds, or one hour. After that time expires, the cache is regenerated.</p>
+<p>You can change the lifetime as follows:

+<p>A value of <code>\Smarty\Smarty::CACHING\_LIFETIME\_SAVED</code> tells Smarty to use the lifetime value at the time the
+cache was generated. This way you can set the just before rendering a template to have granular control over

-<h1 id="objects-advancedfeaturesobjects">Objects {#advanced.features.objects}</h1>
-<p>Smarty allows access to PHP <a href="https://www.php.net/object">objects</a> through
-the templates.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>When you assign/register objects to templates, be sure that all
-properties and methods accessed from the template are for presentation
-purposes only. It is very easy to inject application logic through
-objects, and this leads to poor designs that are difficult to manage.
-See the Best Practices section of the Smarty website.</p>
-</blockquote>
-<p>There are two ways to access them.</p>
+<h1 id="custom-cache-storage-layers">Custom cache storage layers</h1>
+<p>As an alternative to using the default file-based caching mechanism, you
+can specify a custom cache implementation that will be used to read,
+write and clear cached files.</p>
+<p>With a custom cache implementation you could replace the slow filesystem by a
+faster storage engine, centralize the cache to be accessible to multiple
+servers.</p>
+<p>Smarty requires implementations to extend <code>\Smarty\Cacheresource\Base</code>, but encourages you to either extend 
+<code>\Smarty\Cacheresource\Custom</code> or <code>\Smarty\Cacheresource\KeyValueStore</code>.</p>
 <ul>
-<li>
-<p>One way is to <a href="#api.register.object">register objects</a> to the
-    template, then use access them via syntax similar to <a href="#language.custom.functions">custom
-    functions</a>.</p>
-</li>
-<li>
-<p>The other way is to <a href="#api.assign"><code>assign()</code></a> objects to the
-    templates and access them much like any other assigned variable.</p>
-</li>
+<li><code>\Smarty\Cacheresource\Custom</code> is a simple API directing all read, write,
+clear calls to your implementation. This API allows you to store
+wherever and however you deem fit. </li>
+<li><code>\Smarty\Cacheresource\KeyValueStore</code> allows you to turn any 
+KeyValue-Store (like APC or Memcache) into a full-featured
+CacheResource implementation. Everything around deep
+cache-groups like "a|b|c" is being handled for you in a way that
+guarantees clearing the cache-group "a" will clear all nested groups 
+as well - even though KeyValue-Stores don't allow this kind of
+hierarchy by nature.</li>
 </ul>
-<p>The first method has a much nicer template syntax. It is also more
-secure, as a registered object can be restricted to certain methods or
-properties. However, <strong>a registered object cannot be looped over or
-assigned in arrays of objects</strong>, etc. The method you choose will be
-determined by your needs, but use the first method whenever possible to
-keep template syntax to a minimum.</p>
-<p>If security is enabled, no private methods or functions can be accessed
-(beginning with \'_\'). If a method and property of the same name exist,
-the method will be used.</p>
-<p>You can restrict the methods and properties that can be accessed by
-listing them in an array as the third registration parameter.</p>
-<p>By default, parameters passed to objects through the templates are
-passed the same way <a href="#language.custom.functions">custom functions</a> get
-them. An associative array is passed as the first parameter, and the
-smarty object as the second. If you want the parameters passed one at a
-time for each argument like traditional object parameter passing, set
-the fourth registration parameter to FALSE.</p>
-<p>The optional fifth parameter has only effect with <code>format</code> being TRUE
-and contains a list of methods that should be treated as blocks. That
-means these methods have a closing tag in the template
-(<code>{foobar-&gt;meth2}...{/foobar-&gt;meth2}</code>) and the parameters to the methods
-have the same synopsis as the parameters for
-<a href="#plugins.block.functions"><code>block-function-plugins</code></a>: They get the four
-parameters <code>$params</code>, <code>$content</code>, <code>$smarty</code> and <code>&amp;$repeat</code> and they also
-behave like block-function-plugins.</p>
-<div class="highlight"><pre><span></span><code>&lt;?php

-    function meth1($params, $smarty_obj) {

-$smarty-&gt;registerObject(&#39;foobar&#39;,$myobj,array(&#39;meth1&#39;,&#39;meth2&#39;,&#39;prop1&#39;));

-$smarty-&gt;registerObject(&#39;foobar&#39;,$myobj,null,false);

+contents depending on some condition, and you want separate caches for

+<p>Above, we are passing the variable <code>$my_cache_id</code> to
+<a href="#api.display"><code>display()</code></a> as the <code>$cache_id</code>. For each unique value of
+<code>$my_cache_id</code>, a separate cache will be generated for <code>index.tpl</code>. In
+this example, <code>article_id</code> was passed in the URL and is used as the
+<code>$cache_id</code>.</p>
+<blockquote>
+<p><strong>Note</strong></p>
+<p>Be very cautious when passing values from a client (web browser) into
+Smarty or any PHP application. Although the above example of using the
+article_id from the URL looks handy, it could have bad consequences.
+The <code>$cache_id</code> is used to create a directory on the file system, so
+if the user decided to write a script that sends random article_id's at a rapid pace,
+this could possibly cause problems at the server level.
+Be sure to sanitize any data passed in before using it. In this example, you might want to check if
+the article_id is a valid ID in the database.</p>
+</blockquote>
+<p>Be sure to pass the same <code>$cache_id</code> as the second parameter to
+<code>isCached()</code> and <code>clearCache()</code>.</p>

+<p>Even though Smarty runs templates as native PHP for maximum speed, it still needs to 
+execute the PHP code on each call. If your data doesn't change all that often, you
+may be able to speed up your application even more by using output caching.</p>
+<p>Output caching can be a tricky subject, so we devoted an entire <a href="../caching/basics/">section to caching</a>.
+Be sure to read that if you want to use caching.</p>
+<p>By default, Smarty stores caches to PHP-files in a subdirectory named <code>./cache</code>.</p>
+<p>If you need to change this, you can use <code>setCacheDir()</code>.
+Use <code>getCacheDir()</code> to retrieve the configured path.</p>

+<h2 id="disabling-compile-check">Disabling compile check</h2>
+<p>By default, Smarty tests to see if the
+current template has changed since the last time
+it was compiled. If it has changed, it recompiles that template. </p>
+<p>Once an application is put into production, this compile-check step 
+is usually no longer needed and the extra checks can significantly hurt performance. 
+Be sure to disable compile checking on production for maximum performance. 
+<div class="highlight"><pre><span></span><code><a id="__codelineno-4-1" name="__codelineno-4-1" href="#__codelineno-4-1"></a><span class="cp">&lt;?php</span>

+</code></pre></div></p>
+<p>If <a href="../caching/basics/"><code>caching</code></a> is enabled and compile-check is
+enabled, then the cache files will get regenerated if an involved
+template file or config file was updated.</p>
+<h2 id="charset-encoding">Charset encoding</h2>
+<p>There are a variety of encodings for textual data, ISO-8859-1 (Latin1)
+and UTF-8 being the most popular. Unless you change <code>\Smarty\Smarty::$_CHARSET</code>,
+Smarty recognizes <code>UTF-8</code> as the internal charset.</p>
+<blockquote>
+<p><strong>Note</strong></p>
+<p><code>ISO-8859-1</code> has been PHP\'s default internal charset since the
+beginning. Unicode has been evolving since 1991. Since then, it has
+become the one charset to conquer them all, as it is capable of
+encoding most of the known characters even across different character
+systems (latin, cyrillic, japanese, ...). <code>UTF-8</code> is unicode\'s most
+used encoding, as it allows referencing the thousands of character
+with the smallest size overhead possible.</p>
+<p>Since unicode and UTF-8 are very widespread nowadays, their use is
+strongly encouraged.</p>
+<p><strong>Note</strong></p>
+<p>Smarty\'s internals and core plugins are truly UTF-8 compatible since
+Smarty 3.1.</p>

-?&gt;
-</code></pre></div>
-<p>With caching enabled, the function call to <code>display('index.tpl')</code> will
-render the template as usual, but also saves a copy of its output to a
-file (a cached copy) in the <a href="#variable.cache.dir"><code>$cache_dir</code></a>. On the
-next call to <code>display('index.tpl')</code>, the cached copy will be used
-instead of rendering the template again.</p>
+<h1 id="creating-an-extension">Creating an extension</h1>
+<p>In order to organize your custom tags and modifiers, you can create an Extension.
+In fact, most of Smarty itself is organized into two extensions:</p>
+<ul>
+<li>the core extension, which provides the basic language tags such as <code>{if}</code>, <code>{for}</code> and <code>{assign}</code>. </li>
+<li>the default extension, which provides all default modifiers such as <code>|escape</code>,  <code>|nl2br</code> and  <code>|number_format</code> 
+  and tags such as <code>{html_image}</code>, <code>{mailto}</code> and <code>{textformat}</code> that are enabled by default, but not necessarily universal.</li>
+</ul>
 <blockquote>
-<p><strong>Note</strong></p>
-<p>The files in the <a href="#variable.cache.dir"><code>$cache_dir</code></a> are named similar
-to the template name. Although they end in the <code>.php</code> extension, they
-are not intended to be directly executable. Do not edit these files!</p>
+<p><strong> Note </strong></p>
+<p>There is also the 'BCPluginsAdapter' extension, which does not add any new functionality, but
+wraps calls to deprecated methods such as <code>Smarty\Smarty::addPluginsDir()</code> and <code>Smarty\Smarty::loadFilter()</code>.</p>
 </blockquote>
-<p>Each cached page has a limited lifetime determined by
-<a href="#variable.cache.lifetime"><code>$cache_lifetime</code></a>. The default value is 3600
-seconds, or one hour. After that time expires, the cache is regenerated.
-It is possible to give individual caches their own expiration time by
-setting <a href="#variable.caching"><code>$caching</code></a> to
-<code>\Smarty\Smarty::CACHING_LIFETIME_SAVED</code>. See
-<a href="#variable.cache.lifetime"><code>$cache_lifetime</code></a> for more details.</p>
-<div class="highlight"><pre><span></span><code>&lt;?php

-// is set to Smarty::CACHING_LIFETIME_SAVED.

+<p>In order to write your own custom extension, you must write a class that implements <code>Smarty\Extension\ExtensionInterface</code>.
+However, it is usually easier to extend <code>Smarty\Extension\Base</code> which provides empty implementation for each of the methods
+required by <code>Smarty\Extension\ExtensionInterface</code>. This allows you to only override the method(s) you need.</p>

+<p>Writing an extension allows you to add a group of tags, block tags and modifiers to the Smarty language.
+It also allows you to register pre-, post- and output-filters in a structured way. 
+The files in <code>src/Extension/</code> in the <code>smarty/smarty</code> dir should give you all the information you need to start
+writing your own extension.</p>

+other context. Smarty comes with a bunch of <a href="../../../designers/language-modifiers/">modifiers</a>, but you can 
+easily add your own.</p>
+<p>In order to do so, you must write a function that accepts as its first parameter the value on which the
+modifier is to operate. The rest of the parameters are optional, depending on what kind of operation is to be performed.</p>
+<p>The modifier has to return the result of its processing.</p>
+<p>For example:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-0-1" name="__codelineno-0-1" href="#__codelineno-0-1"></a><span class="cp">&lt;?php</span>

 <p>Template prefilters are PHP functions that your templates are ran
 through <em>before they are compiled</em>. This is good for preprocessing your
 templates to remove unwanted comments, keeping an eye on what people are
 putting in their templates, etc.</p>
-<p>Prefilters can be either <a href="#api.register.filter">registered</a> or loaded
-from the <a href="#variable.plugins.dir">plugins directory</a> by using
-<a href="#api.load.filter"><code>loadFilter()</code></a> function.</p>
 <p>Smarty will pass the template source code as the first argument, and
 expect the function to return the resulting template source code.</p>
-<p>This will remove all the html comments in the template source.</p>
-<div class="highlight"><pre><span></span><code>&lt;?php

+<p>First, create a base template with one or more <a href="../../designers/language-builtin-functions/language-function-block/">blocks</a>. 
+Then, create a child template. The child template

-section for how to use the functions for individual templates.</p>
+<p>When <a href="../configuring/#disabling-compile-check">compile-check</a> is enabled, all files 
+in the inheritance tree

+<a href="../../designers/language-builtin-functions/language-function-include/"><code>{include}</code></a> and it contains
+<a href="../../designers/language-builtin-functions/language-function-block/"><code>{block}</code></a> areas it works only if the

+a surrounding <a href="../../designers/language-builtin-functions/language-function-block/"><code>{block}</code></a>. In the final

+<p>Instead of using <a href="../../designers/language-builtin-functions/language-function-extends/"><code>{extends}</code></a> tags in the

-<p>Version 2.0 introduced the plugin architecture that is used for almost
-all the customizable functionality of Smarty. This includes:</p>
-<ul>
-<li>
-<p>functions</p>
-</li>
-<li>
-<p>modifiers</p>
-</li>
-<li>
-<p>block functions</p>

-<li>
-<p>resources</p>
-</li>
-<li>
-<p>inserts</p>
-</li>
-</ul>
-<p>With the exception of resources, backwards compatibility with the old
-way of registering handler functions via register_* API is preserved.
-If you did not use the API but instead modified the class variables
-<code>$custom_funcs</code>, <code>$custom_mods</code>, and other ones directly, then you will
-need to adjust your scripts to either use the API or convert your custom
-functionality into plugins.</p>

+<p>As explained in <a href="../basics/">basics</a>, you can use <code>$smarty-&gt;fetch()</code> or <code>$smarty-&gt;display()</code>

+<p>When you use <code>display()</code>, Smarty renders the template to the standard output stream.
+<code>fetch()</code> returns the output instead of echoing it.</p>
+<p>The example above uses simple filenames to load the template. Smarty also supports
+<a href="../resources/">loading templates from resources</a>.</p>
+<h2 id="creating-a-template-object">Creating a template object</h2>
+<p>You can also create a template object which later can be prepared first,
+and rendered later. This can be useful, for example if you plan to re-use several 
+templates.</p>

+<p>You can use <code>templateExists()</code> to check whether a template exists before you attempt to use it.</p>
+<p>It accepts either a path to the template on the filesystem or a
+resource string specifying the template.</p>
+<p>This example uses <code>$_GET['page']</code> to
+<a href="../../designers/language-builtin-functions/language-function-include/"><code>{include}</code></a> a content template. If the

+<h1 id="template-resources">Template resources</h1>
+<h2 id="the-filesystem-resource">The filesystem resource</h2>
+<p>So far in our examples, we have used simple filenames or paths when loading a template.</p>
+<p>For example, to load a template file called <code>homepage.tpl</code>, from the filesystem, you could write:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-0-1" name="__codelineno-0-1" href="#__codelineno-0-1"></a><span class="cp">&lt;?php</span>
+<a id="__codelineno-0-2" name="__codelineno-0-2" href="#__codelineno-0-2"></a>
+<a id="__codelineno-0-3" name="__codelineno-0-3" href="#__codelineno-0-3"></a><span class="k">use</span> <span class="nx">Smarty\Smarty</span><span class="p">;</span>
+<a id="__codelineno-0-4" name="__codelineno-0-4" href="#__codelineno-0-4"></a><span class="nv">$smarty</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">Smarty</span><span class="p">();</span>
+<a id="__codelineno-0-5" name="__codelineno-0-5" href="#__codelineno-0-5"></a>
+<a id="__codelineno-0-6" name="__codelineno-0-6" href="#__codelineno-0-6"></a><span class="nv">$smarty</span><span class="o">-&gt;</span><span class="na">display</span><span class="p">(</span><span class="s1">&#39;homepage.tpl&#39;</span><span class="p">);</span>
+</code></pre></div></p>
+<p>The filesystem is the default resource. Templates, however, may come 
+from a variety of sources. When you render a template, or
+when you include a template from within another template, you supply a
+resource type, followed by <code>:</code> and the appropriate path and template name.</p>
+<p>If a resource is not explicitly given, the default resource type is assumed.
+The resource type for the filesystem is <code>file</code>, which means that the previous example
+can be rewritten as follows:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-1-1" name="__codelineno-1-1" href="#__codelineno-1-1"></a><span class="cp">&lt;?php</span>
+<a id="__codelineno-1-2" name="__codelineno-1-2" href="#__codelineno-1-2"></a>
+<a id="__codelineno-1-3" name="__codelineno-1-3" href="#__codelineno-1-3"></a><span class="k">use</span> <span class="nx">Smarty\Smarty</span><span class="p">;</span>
+<a id="__codelineno-1-4" name="__codelineno-1-4" href="#__codelineno-1-4"></a><span class="nv">$smarty</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">Smarty</span><span class="p">();</span>
+<a id="__codelineno-1-5" name="__codelineno-1-5" href="#__codelineno-1-5"></a>
+<a id="__codelineno-1-6" name="__codelineno-1-6" href="#__codelineno-1-6"></a><span class="nv">$smarty</span><span class="o">-&gt;</span><span class="na">display</span><span class="p">(</span><span class="s1">&#39;file:homepage.tpl&#39;</span><span class="p">);</span>
+</code></pre></div></p>
+<p>The file resource pulls templates source files from the directories
+specified using <code>Smarty::setTemplateDir()</code> (see <a href="../configuring/">Configuring Smarty</a>).</p>
+<p><code>setTemplateDir</code> accepts a single path, but can also ben called with an array of paths. 
+In that case, the list of directories is traversed in the order they appear in the array. The
+first template found is the one to process.</p>
+<h3 id="templates-from-a-specific-directory">Templates from a specific directory</h3>
+<p>Smarty 3.1 introduced the bracket-syntax for specifying an element from
+<code>Smarty::setTemplateDir()</code>. This allows websites
+employing multiple sets of templates better control over which template
+to access.</p>
+<p>The bracket-syntax can be used as follows:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-2-1" name="__codelineno-2-1" href="#__codelineno-2-1"></a><span class="cp">&lt;?php</span>

+<h2 id="the-string-and-eval-resources">The string and eval resources</h2>
+<p>Smarty can render templates from a string by using the <code>string:</code> or
+<code>eval:</code> resource.</p>
+<ul>
+<li>
+<p>The <code>string:</code> resource behaves much the same as a template file. The
+    template source is compiled from a string and stores the compiled
+    template code for later reuse. Each unique template string will
+    create a new compiled template file. If your template strings are
+    accessed frequently, this is a good choice. If you have frequently
+    changing template strings (or strings with low reuse value), the
+    <code>eval:</code> resource may be a better choice, as it doesn\'t save
+    compiled templates to disk.</p>
+</li>
+<li>
+<p>The <code>eval:</code> resource evaluates the template source every time a page
+    is rendered. This is a good choice for strings with low reuse value.
+    If the same string is accessed frequently, the <code>string:</code> resource
+    may be a better choice.</p>
+</li>
+</ul>
+<blockquote>
+<p><strong>Note</strong></p>
+<p>With a <code>string:</code> resource type, each unique string generates a
+compiled file. Smarty cannot detect a string that has changed, and
+therefore will generate a new compiled file for each unique string. It
+is important to choose the correct resource so that you do not fill
+your disk space with wasted compiled strings.</p>

+<blockquote>
+<p><strong>Note</strong></p>
+<p>Using the extends resource is usually not necessary. If you have a choice, it is normally more flexible and

+<p>When <code>string:</code> and <code>eval:</code> templates are used, make sure they are properly url or base64 encoded. </p>
+<p>The templates within an inheritance chain are not compiled separately. Only a single compiled template will be generated.

+for example to load template from a database.</p>
+<p>For example:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-15-1" name="__codelineno-15-1" href="#__codelineno-15-1"></a><span class="cp">&lt;?php</span>

+</code></pre></div></p>
+<p>If a Resource's templates should not be run through the Smarty
+compiler, the Custom Resource may extend <code>\Smarty\Resource\UncompiledPlugin</code>.
+The Resource Handler must then implement the function
+<code>renderUncompiled(\Smarty\Template $_template)</code>. <code>$_template</code> is
+a reference to the current template and contains all assigned variables
+which the implementor can access via
+<code>$_template-&gt;getSmarty()-&gt;getTemplateVars()</code>. These Resources simply echo
+their rendered content to the output stream. The rendered output will be
+output-cached if the Smarty instance was configured accordingly. See
+<code>src/Resource/PhpPlugin.php</code> for an example.</p>
+<p>If the Resource's compiled templates should not be cached on disk, the
+Custom Resource may extend <code>\Smarty\Resource\RecompiledPlugin</code>. These Resources
+are compiled every time they are accessed. This may be an expensive
+overhead. See <code>src/Resource/StringEval.php</code> for an
+example.</p>
+<h2 id="changing-the-default-resource-type">Changing the default resource type</h2>
+<p>The default resource type is <code>file</code>. If you want to change it, use <code>Smarty::setDefaultResourceType</code>.</p>
+<p>The following example will change the default resource type to <code>mysql</code>:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-16-1" name="__codelineno-16-1" href="#__codelineno-16-1"></a><span class="cp">&lt;?php</span>
+<a id="__codelineno-16-2" name="__codelineno-16-2" href="#__codelineno-16-2"></a><span class="nv">$smarty</span><span class="o">-&gt;</span><span class="na">setDefaultResourceType</span><span class="p">(</span><span class="s1">&#39;mysql&#39;</span><span class="p">);</span>
+</code></pre></div></p>

-<h1 id="charset-encoding">Charset Encoding</h1>
-<p>There are a variety of encodings for textual data, ISO-8859-1 (Latin1)
-and UTF-8 being the most popular. Unless you change <code>\Smarty\Smarty::$_CHARSET</code>, 
-Smarty recognizes <code>UTF-8</code> as the internal charset.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p><code>ISO-8859-1</code> has been PHP\'s default internal charset since the
-beginning. Unicode has been evolving since 1991. Since then it has
-become the one charset to conquer them all, as it is capable of
-encoding most of the known characters even across different character
-systems (latin, cyrillic, japanese, ...). <code>UTF-8</code> is unicode\'s most
-used encoding, as it allows referencing the thousands of character
-with the smallest size overhead possible.</p>
-<p>Since unicode and UTF-8 are very wide spread nowadays, their use is
-strongly encouraged.</p>
-<p><strong>Note</strong></p>
-<p>Smarty\'s internals and core plugins are truly UTF-8 compatible since
-Smarty 3.1.</p>

+<h1 id="security">Security</h1>
+<p>Security is good for situations when you have untrusted parties editing
+the templates, and you want to reduce the risk of system
+security compromises through the template language.</p>
+<p>The settings of the security policy are defined by overriding public properties of an
+instance of the \Smarty\Security class. These are the possible settings:</p>
+<ul>
+<li><code>$secure_dir</code> is an array of template directories that are
+    considered secure. A directory configured using <code>$smarty-&gt;setTemplateDir()</code> is
+    considered secure implicitly. The default is an empty array.</li>
+<li><code>$trusted_uri</code> is an array of regular expressions matching URIs that
+  are considered trusted. This security directive is used by
+  <a href="../../designers/language-custom-functions/language-function-fetch/"><code>{fetch}</code></a> and
+  <a href="../../designers/language-custom-functions/language-function-html-image/"><code>{html_image}</code></a>. URIs passed to
+  these functions are reduced to <code>{$PROTOCOL}://{$HOSTNAME}</code> to allow
+  simple regular expressions (without having to deal with edge cases
+  like authentication-tokens).</li>
+</ul>
+<p>The expression <code>'#https?://.*smarty.net$#i'</code> would allow accessing
+  the following URIs:</p>
+<div class="highlight"><pre><span></span><code>-   `http://smarty.net/foo`
+-   `http://smarty.net/foo`
+-   `http://www.smarty.net/foo`
+-   `http://smarty.net/foo`
+-   `https://foo.bar.www.smarty.net/foo/bla?blubb=1`
+</code></pre></div>
+<p>but deny access to these URIs:</p>
+<div class="highlight"><pre><span></span><code>-   `http://smarty.com/foo` (not matching top-level domain \&quot;com\&quot;)
+-   `ftp://www.smarty.net/foo` (not matching protocol \&quot;ftp\&quot;)
+-   `http://www.smarty.net.otherdomain.com/foo` (not matching end of
+    domain \&quot;smarty.net\&quot;)
+</code></pre></div>
+<ul>
+<li>
+<p><code>$static_classes</code> is an array of classes that are considered
+    trusted. The default is an empty array which allows access to all
+    static classes. To disable access to all static classes set
+    $static_classes = null.</p>
+</li>
+<li>
+<p><code>$streams</code> is an array of streams that are considered trusted and
+    can be used from within template. To disable access to all streams
+    set $streams = null. An empty array ( $streams = [] ) will
+    allow all streams. The default is array('file').</p>
+</li>
+<li>
+<p><code>$allowed_modifiers</code> is an array of (registered / autoloaded)
+    modifiers that should be accessible to the template. If this array
+    is non-empty, only the herein listed modifiers may be used. This is
+    a whitelist.</p>
+</li>
+<li>
+<p><code>$disabled_modifiers</code> is an array of (registered / autoloaded)
+    modifiers that may not be accessible to the template.</p>
+</li>
+<li>
+<p><code>$allowed_tags</code> is a boolean flag which controls if constants can
+    function-, block and filter plugins that should be accessible to the
+    template. If this array is non-empty, only the herein listed
+    modifiers may be used. This is a whitelist.</p>
+</li>
+<li>
+<p><code>$disabled_tags</code> is an array of (registered / autoloaded) function-,
+    block and filter plugins that may not be accessible to the template.</p>
+</li>
+<li>
+<p><code>$allow_constants</code> is a boolean flag which controls if constants can
+    be accessed by the template. The default is "true".</p>
+</li>
+<li>
+<p><code>$allow_super_globals</code> is a boolean flag which controls if the PHP
+    super globals can be accessed by the template. The default is
+    "true".</p>
+</li>
+</ul>
+<p>If security is enabled, no private methods, functions or properties of
+static classes or assigned objects can be accessed (beginning with
+'_') by the template.</p>
+<p>To customize the security policy settings you can extend the
+\Smarty\Security class or create an instance of it.</p>

+<h1 id="assigning-variables">Assigning variables</h1>
+<p>Templates start to become really useful once you know how to use variables.</p>
+<h2 id="basic-assigning">Basic assigning</h2>
+<p>Let's revisit the example from the <a href="../../basics/">basics section</a>. The following script assigns a value to 
+the 'companyName' variable and renders the template:</p>
+<div class="highlight"><pre><span></span><code><a id="__codelineno-0-1" name="__codelineno-0-1" href="#__codelineno-0-1"></a><span class="cp">&lt;?php</span>
+<a id="__codelineno-0-2" name="__codelineno-0-2" href="#__codelineno-0-2"></a>

+<a id="__codelineno-0-7" name="__codelineno-0-7" href="#__codelineno-0-7"></a>
+<a id="__codelineno-0-8" name="__codelineno-0-8" href="#__codelineno-0-8"></a><span class="nv">$smarty</span><span class="o">-&gt;</span><span class="na">display</span><span class="p">(</span><span class="s1">&#39;footer.tpl&#39;</span><span class="p">);</span>
+</code></pre></div>
+<p>footer.tpl:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-1-1" name="__codelineno-1-1" href="#__codelineno-1-1"></a><span class="x">&lt;small&gt;Copyright </span><span class="cp">{</span><span class="nv">$companyName</span><span class="o">|</span><span class="na">escape</span><span class="cp">}</span><span class="x">&lt;/small&gt;</span>
+</code></pre></div></p>
+<p>Smarty will apply the <a href="../designers/language-modifiers/language-modifier-escape.md">escape modifier</a>
+to the value assigned to the variable
+<code>companyName</code> and replace <code>{$companyName|escape}</code> with the result.</p>
+<div class="highlight"><pre><span></span><code><a id="__codelineno-2-1" name="__codelineno-2-1" href="#__codelineno-2-1"></a><span class="p">&lt;</span><span class="nt">small</span><span class="p">&gt;</span>Copyright AC <span class="ni">&amp;amp;</span> ME Corp.<span class="p">&lt;/</span><span class="nt">small</span><span class="p">&gt;</span>
+</code></pre></div>
+<p>Using <code>$smarty-&gt;assign()</code> is the most common way of assigning data to templates, but there are several other methods.</p>
+<h2 id="appending-data-to-an-existing-variable">Appending data to an existing variable</h2>
+<p>Using <code>append()</code>, you can add data to an existing variable, usually an array.</p>
+<p>If you append to a string value, it is converted to an array value and
+then appended to. You can explicitly pass name/value pairs, or
+associative arrays containing the name/value pairs. If you pass the
+optional third parameter of TRUE, the value will be merged with the
+current array instead of appended.</p>
+<p>Examples:</p>
+<div class="highlight"><pre><span></span><code><a id="__codelineno-3-1" name="__codelineno-3-1" href="#__codelineno-3-1"></a><span class="cp">&lt;?php</span>

+<p>When you use a template objects, as explained in <a href="../../rendering/#creating-a-template-object">rendering a template</a>,

+<h2 id="using-data-objects">Using data objects</h2>
+<p>For more complex use cases, Smarty supports the concept of data objects.
+Data objects are containers to hold data. Data objects can be attached to templates when creating them.
+This allows for fine-grained re-use of data.</p>
+<p>For example:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-5-1" name="__codelineno-5-1" href="#__codelineno-5-1"></a><span class="cp">&lt;?php</span>

+<p>Note that there it's only useful to clear assigned data if you:</p>
+<ol>
+<li>repeatedly re-use templates, and</li>
+<li>the variables used may change on each repetition</li>
+</ol>
+<p>If your script simply runs once and then ends, or you always assign the same variables, clearing assigned data 
+is of no use.</p>

+<h2 id="example-config-file">Example config file</h2>
+<p>Config files are best suited to manage template settings

+<p>Values of <a href="./language-variables/language-config-variables.md">config file variables</a> can be in
+quotes, but not necessary. You can use either single or double quotes.
+If you have a value that spans more than one line, enclose the entire
+value with triple quotes ("""). You can put comments into config
+files by any syntax that is not a valid config file syntax. We recommend
+using a <code>#</code> (hash) at the beginning of the line.</p>
+<p>The example config file above has two sections. Section names are
+enclosed in [brackets]. Section names can be arbitrary strings not
+containing <code>[</code> or <code>]</code> symbols. The variable at the top is a global
+variable. Global variables are always
+loaded from the config file. If a particular section is loaded, then the
+global variables and the variables from that section are also loaded. If
+a variable exists both as a global and in a section, the section
+variable is used.</p>
+<h2 id="loading-a-config-file">Loading a config file</h2>
+<p>Config files are loaded into templates with the built-in template
+function <a href="../../../designers/language-builtin-functions/language-function-config-load/"><code>{config_load}</code></a> or by calling

-<p>You can specify a function that is used to retrieve template contents in

-this is to create templates that do not exist on-the-fly.</p>
-<p>See also <a href="#advanced.features.streams"><code>Streams</code></a></p>

+<h2 id="retrieving-config-variables-in-php">Retrieving config variables in PHP</h2>
+<h2 id="loading-from-a-resource">Loading from a resource</h2>
+<p>Config files (or resources) are loaded by the same resource facilities
+as templates. That means that a config file can also be loaded from a db. See <a href="../../resources/">resources</a>
+for more information.</p>
+<h2 id="config-overwrite">Config overwrite</h2>
+<p>If you name two variables the same within a section,
+the last one will be used unless you call:

+<h1 id="objects">Objects</h1>
+<p>Smarty allows access to PHP <a href="https://www.php.net/object">objects</a> through
+the templates.</p>
+<blockquote>
+<p><strong>Note</strong></p>
+<p>When you assign/register objects to templates, be sure that all
+properties and methods accessed from the template are for presentation
+purposes only. It is very easy to inject application logic through
+objects, and this leads to poor designs that are difficult to manage.
+See the Best Practices section of the Smarty website.</p>
+</blockquote>
+<p>There are two ways to access them.</p>
+<h2 id="assign-the-object">Assign the object</h2>
+<p>You can assign objects to a template and access them much like any other assigned variable.</p>
+<p>Example:
+<div class="highlight"><pre><span></span><code><a id="__codelineno-0-1" name="__codelineno-0-1" href="#__codelineno-0-1"></a><span class="cp">&lt;?php</span>

+</code></pre></div></p>
+<p>And here's how to access your object in <code>index.tpl</code>:</p>
+<div class="highlight"><pre><span></span><code><a id="__codelineno-1-1" name="__codelineno-1-1" href="#__codelineno-1-1"></a><span class="cp">{</span><span class="nv">$myobj</span><span class="o">-&gt;</span><span class="na">meth1</span><span class="o">(</span><span class="s1">&#39;foo&#39;</span><span class="o">,</span><span class="nv">$bar</span><span class="o">)</span><span class="cp">}</span>
+</code></pre></div>
+<h2 id="register-the-object">Register the object</h2>
+<p>Registerd objects use a different template syntax. Also, a registered object 
+can be restricted to certain methods or
+properties. However, <strong>a registered object cannot be looped over or
+assigned in arrays of objects</strong>, etc.</p>
+<p>If security is enabled, no private methods or functions can be accessed
+(beginning with '_'). If a method and property of the same name exist,
+the method will be used.</p>
+<p>You can restrict the methods and properties that can be accessed by
+listing them in an array as the third registration parameter.</p>
+<p>By default, parameters passed to objects through the templates are
+passed the same way <a href="../../../designers/language-custom-functions/">custom functions</a> get
+them. An associative array is passed as the first parameter, and the
+smarty object as the second. If you want the parameters passed one at a
+time for each argument like traditional object parameter passing, set
+the fourth registration parameter to FALSE.</p>
+<p>The optional fifth parameter has only effect with <code>format</code> being TRUE
+and contains a list of methods that should be treated as blocks. That
+means these methods have a closing tag in the template
+(<code>{foobar-&gt;meth2}...{/foobar-&gt;meth2}</code>) and the parameters to the methods
+have the same synopsis as the parameters for
+<a href="../../extending/block-tags/"><code>block tags</code></a>: They get the four
+parameters <code>$params</code>, <code>$content</code>, <code>$smarty</code> and <code>&amp;$repeat</code> and they also
+behave like block tags.</p>

-<h1 id="security-advancedfeaturessecurity">Security {#advanced.features.security}</h1>
-<p>Security is good for situations when you have untrusted parties editing
-the templates e.g. via ftp, and you want to reduce the risk of system
-security compromises through the template language.</p>
-<p>The settings of the security policy are defined by properties of an
-instance of the Smarty_Security class. These are the possible settings:</p>
-<ul>
-<li>
-<p><code>$secure_dir</code> is an array of template directories that are
-    considered secure. <a href="#variable.template.dir"><code>$template_dir</code></a>
-    considered secure implicitly. The default is an empty array.</p>
-</li>
-<li>
-<p><code>$trusted_uri</code> is an array of regular expressions matching URIs that
-    are considered trusted. This security directive used by
-    <a href="#language.function.fetch"><code>{fetch}</code></a> and
-    <a href="#language.function.html.image"><code>{html_image}</code></a>. URIs passed to
-    these functions are reduced to <code>{$PROTOCOL}://{$HOSTNAME}</code> to allow
-    simple regular expressions (without having to deal with edge cases
-    like authentication-tokens).</p>
-<p>The expression <code>'#https?://.*smarty.net$#i'</code> would allow accessing
-the following URIs:</p>
-<ul>
-<li>
-<p><code>http://smarty.net/foo</code></p>
-</li>
-<li>
-<p><code>http://smarty.net/foo</code></p>
-</li>
-<li>
-<p><code>http://www.smarty.net/foo</code></p>
-</li>
-<li>
-<p><code>http://smarty.net/foo</code></p>
-</li>
-<li>
-<p><code>https://foo.bar.www.smarty.net/foo/bla?blubb=1</code></p>
-</li>
-</ul>
-<p>but deny access to these URIs:</p>
-<ul>
-<li>
-<p><code>http://smarty.com/foo</code> (not matching top-level domain \"com\")</p>
-</li>
-<li>
-<p><code>ftp://www.smarty.net/foo</code> (not matching protocol \"ftp\")</p>
-</li>
-<li>
-<p><code>http://www.smarty.net.otherdomain.com/foo</code> (not matching end of
-    domain \"smarty.net\")</p>
-</li>
-</ul>
-</li>
-<li>
-<p><code>$static_classes</code> is an array of classes that are considered
-    trusted. The default is an empty array which allows access to all
-    static classes. To disable access to all static classes set
-    \$static_classes = null.</p>
-</li>
-<li>
-<p><code>$streams</code> is an array of streams that are considered trusted and
-    can be used from within template. To disable access to all streams
-    set \$streams = null. An empty array ( \$streams = array() ) will
-    allow all streams. The default is array(\'file\').</p>
-</li>
-<li>
-<p><code>$allowed_modifiers</code> is an array of (registered / autoloaded)
-    modifiers that should be accessible to the template. If this array
-    is non-empty, only the herein listed modifiers may be used. This is
-    a whitelist.</p>
-</li>
-<li>
-<p><code>$disabled_modifiers</code> is an array of (registered / autoloaded)
-    modifiers that may not be accessible to the template.</p>
-</li>
-<li>
-<p><code>$allowed_tags</code> is a boolean flag which controls if constants can
-    function-, block and filter plugins that should be accessible to the
-    template. If this array is non-empty, only the herein listed
-    modifiers may be used. This is a whitelist.</p>
-</li>
-<li>
-<p><code>$disabled_tags</code> is an array of (registered / autoloaded) function-,
-    block and filter plugins that may not be accessible to the template.</p>
-</li>
-<li>
-<p><code>$allow_constants</code> is a boolean flag which controls if constants can
-    be accessed by the template. The default is \"true\".</p>
-</li>
-<li>
-<p><code>$allow_super_globals</code> is a boolean flag which controls if the PHP
-    super globals can be accessed by the template. The default is
-    \"true\".</p>
-</li>
-</ul>
-<p>If security is enabled, no private methods, functions or properties of
-static classes or assigned objects can be accessed (beginning with
-\'_\') by the template.</p>
-<p>To customize the security policy settings you can extend the
-Smarty_Security class or create an instance of it.</p>
-<div class="highlight"><pre><span></span><code>&lt;?php
-
-use Smarty\Smarty;
-
-class My_Security_Policy extends \Smarty\Security {
-  public $allow_constants = false;
-}
-$smarty = new Smarty();
-// enable security
-$smarty-&gt;enableSecurity(&#39;My_Security_Policy&#39;);
-?&gt;
-
-
-&lt;?php
-use Smarty\Smarty;
-$smarty = new Smarty();
-$my_security_policy = new \Smarty\Security($smarty);
-$my_security_policy-&gt;allow_constants = false;
-// enable security
-$smarty-&gt;enableSecurity($my_security_policy);
-?&gt;
-
-
-&lt;?php
-use Smarty\Smarty;
-$smarty = new Smarty();
-// enable default security
-$smarty-&gt;enableSecurity();
-?&gt;
-</code></pre></div>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>Most security policy settings are only checked when the template gets
-compiled. For that reason you should delete all cached and compiled
-template files when you change your security settings.</p>
-</blockquote>

-<p>You can directly access static classes. The syntax is the same as in
-PHP.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>Direct access to PHP classes is not recommended. This ties the
-underlying application code structure directly to the presentation,
-and also complicates template syntax. It is recommended to register
-plugins which insulate templates from PHP classes/objects. Use at your
-own discretion. See the Best Practices section of the Smarty website.</p>

-<h1 id="template-inheritance-advancedfeaturestemplateinheritance">Template Inheritance {#advanced.features.template.inheritance}</h1>
-<p>Inheritance brings the concept of Object Oriented Programming to
-templates, allowing you to define one (or more) base templates that can
-be extended by child templates. Extending means that the child template
-can override all or some of the parent named block areas.</p>
-<ul>
-<li>
-<p>The inheritance tree can be as deep as you want, meaning you can
-    extend a file that extends another one that extends another one and
-    so on.</p>
-</li>
-<li>
-<p>The child templates can not define any content besides what\'s
-    inside <a href="#language.function.block"><code>{block}</code></a> tags they override.
-    Anything outside of <a href="#language.function.block"><code>{block}</code></a> tags will
-    be removed.</p>
-</li>
-<li>
-<p>The content of <a href="#language.function.block"><code>{block}</code></a> tags from child
-    and parent templates can be merged by the <code>append</code> or <code>prepend</code>
-    <a href="#language.function.block"><code>{block}</code></a> tag option flags and
-    <code>{$smarty.block.parent}</code> or <code>{$smarty.block.child}</code> placeholders.</p>
-</li>
-<li>
-<p>Template inheritance is a compile time process which creates a
-    single compiled template file. Compared to corresponding solutions
-    based on subtemplates included with the
-    <a href="#language.function.include"><code>{include}</code></a> tag it does have much
-    better performance when rendering.</p>
-</li>
-<li>
-<p>The child template extends its parent defined with the
-    <a href="#language.function.extends"><code>{extends}</code></a> tag, which must be the
-    first line in the child template. Instead of using the
-    <a href="#language.function.extends"><code>{extends}</code></a> tags in the template files
-    you can define the whole template inheritance tree in the PHP script
-    when you are calling <a href="#api.fetch"><code>fetch()</code></a> or
-    <a href="#api.display"><code>display()</code></a> with the <code>extends:</code> template resource
-    type. The later provides even more flexibility.</p>
-</li>
-</ul>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>When <code>$compile_check</code> is enabled, all files in the inheritance tree
-are checked for modifications upon each invocation. You may want to
-disable <code>$compile_check</code> on production servers for this reason.</p>
-<p><strong>Note</strong></p>
-<p>If you have a subtemplate which is included with
-<a href="#language.function.include"><code>{include}</code></a> and it contains
-<a href="#language.function.block"><code>{block}</code></a> areas it works only if the
-<a href="#language.function.include"><code>{include}</code></a> itself is called from within
-a surrounding <a href="#language.function.block"><code>{block}</code></a>. In the final
-parent template you may need a dummy
-<a href="#language.function.block"><code>{block}</code></a> for it.</p>
-</blockquote>
-<p>layout.tpl (parent)</p>
-<div class="highlight"><pre><span></span><code>&lt;html&gt;
-&lt;head&gt;
-  &lt;title&gt;{block name=title}Default Page Title{/block}&lt;/title&gt;
-  {block name=head}{/block}
-&lt;/head&gt;
-&lt;body&gt;
-{block name=body}{/block}

-  &lt;link href=&quot;/css/mypage.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot;/&gt;
-  &lt;script src=&quot;/js/mypage.js&quot;&gt;&lt;/script&gt;
-{/block}
-</code></pre></div>
-<p>mypage.tpl (grandchild)</p>
-<div class="highlight"><pre><span></span><code>{extends file=&#39;myproject.tpl&#39;}
-{block name=title}My Page Title{/block}
-{block name=head}
-  &lt;link href=&quot;/css/mypage.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot;/&gt;
-  &lt;script src=&quot;/js/mypage.js&quot;&gt;&lt;/script&gt;
-{/block}
-{block name=body}My HTML Page Body goes here{/block}
-</code></pre></div>
-<p>To render the above use</p>
-<div class="highlight"><pre><span></span><code> $smarty-&gt;display(&#39;mypage.tpl&#39;);
-</code></pre></div>
-<p>The resulting output is</p>
-<div class="highlight"><pre><span></span><code>&lt;html&gt;
-&lt;head&gt;
-  &lt;title&gt;My Page Title&lt;/title&gt;
-  &lt;link href=&quot;/css/mypage.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot;/&gt;
-  &lt;script src=&quot;/js/mypage.js&quot;&gt;&lt;/script&gt;
-&lt;/head&gt;
-&lt;body&gt;
-My HTML Page Body goes here
-&lt;/body&gt;
-&lt;/html&gt;
-</code></pre></div>
-<p>Instead of using <a href="#language.function.extends"><code>{extends}</code></a> tags in the
-template files you can define the inheritance tree in your PHP script by
-using the <a href="#resources.extends"><code>extends:</code> resource</a> type.</p>

-<h1 id="changing-settings-by-template-advancedfeaturestemplatesettings">Changing settings by template {#advanced.features.template.settings}</h1>
-<p>Normally you configure the Smarty settings by modifying the
-<a href="#api.variables"><code>Smarty class variables</code></a>. Furthermore you can register
-plugins, filters etc. with <a href="#api.functions"><code>Smarty functions</code></a>.
-Modifications done to the Smarty object will be global for all
-templates.</p>
-<p>However the Smarty class variables and functions can be accessed or
-called by individual template objects. Modification done to a template
-object will apply only for that template and its included subtemplates.</p>
-<div class="highlight"><pre><span></span><code>&lt;?php

-<h1 id="controlling-cacheability-of-output-cachingcacheable">Controlling Cacheability of Output {#caching.cacheable}</h1>
-<p>If caching is enabled normally the whole final output of the page gets
-cached. However Smarty3 offers several options how to exclude sections
-of your output from caching.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>Be sure any variables used within a non-cached section are also
-assigned from PHP when the page is loaded from the cache.</p>
-</blockquote>
-<h2 id="cacheability-of-template-section-cacheabilitysections">Cacheability of Template Section {#cacheability.sections}</h2>
-<p>A larger section of your template can easily excluded from caching by
-using the <a href="#language.function.nocache"><code>{nocache}</code></a> and
-<a href="#language.function.nocache"><code>{/nocache}</code></a> tags.</p>
-<div class="highlight"><pre><span></span><code>Today&#39;s date is
-{nocache}
-{$smarty.now|date_format}
-{/nocache}
-</code></pre></div>
-<p>The above code will output the current date on a cached page.</p>
-<h2 id="cacheability-of-tags-cacheabilitytags">Cacheability of Tags {#cacheability.tags}</h2>
-<p>Caching for an individual tag can be disabled by adding the \"nocache\"
-option flag to the tag.</p>
-<div class="highlight"><pre><span></span><code>Today&#39;s date is
-{$smarty.now|date_format nocache}
-</code></pre></div>
-<h2 id="cacheability-of-variables-cacheabilityvariables">Cacheability of Variables {#cacheability.variables}</h2>
-<p>You can <a href="#api.assign"><code>assign()</code></a> variables as not cachable. Any tag
-which uses such variable will be automatically executed in nocache mode.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>If a tag is executed in nocache mode you must make sure that all other
-variables used by that tag are also assigned from PHP when the page is
-loaded from the cache.</p>
-<p><strong>Note</strong></p>
-<p>The nocache status of an assigned variable will effect the compiled
-template code. If you change the status you must manually delete
-existing compiled and cached template files to force a recompile.</p>
-</blockquote>
-<div class="highlight"><pre><span></span><code>// assign $foo as nocahe variable
-$smarty-&gt;assign(&#39;foo&#39;,time(),true);
 
 
-Dynamic time value is {$foo}
-</code></pre></div>
-<h2 id="cacheability-of-plugins-cacheabilityplugins">Cacheability of Plugins {#cacheability.plugins}</h2>
-<p>The cacheability of plugins can be declared when registering them. The
-third parameter to <a href="#api.register.plugin"><code>registerPlugin()</code></a> is called
-<code>$cacheable</code> and defaults to TRUE.</p>
-<p>When registering a plugin with <code>$cacheable=false</code> the plugin is called
-everytime the page is displayed, even if the page comes from the cache.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>The <code>$cacheable</code> status will affect the compiled template code. If you
-change the status you must manually delete existing compiled and
-cached template files to force a recompile.</p>
-</blockquote>
-<p>Example <code>index.php</code>:</p>
-<div class="highlight"><pre><span></span><code>&lt;?php
-$smarty-&gt;setCaching(Smarty::CACHING_LIFETIME_CURRENT);
-
-function smarty_block_dynamic($param, $content, $smarty) {
-    return $content;
-}
-$smarty-&gt;registerPlugin(&#39;block&#39;,&#39;dynamic&#39;, &#39;smarty_block_dynamic&#39;, false);
-
-$smarty-&gt;display(&#39;index.tpl&#39;);
-?&gt;
-</code></pre></div>
-<p>where <code>index.tpl</code> is:</p>
-<div class="highlight"><pre><span></span><code>Page created: {&#39;0&#39;|date_format:&#39;%D %H:%M:%S&#39;}
-
-{dynamic}
-
-Now is: {&#39;0&#39;|date_format:&#39;%D %H:%M:%S&#39;}
-
-... do other stuff ...
-
-{/dynamic}
-</code></pre></div>
-<p>When reloading the page you will notice that both dates differ. One is
-"dynamic" one is "static". You can do everything between
-<code>{dynamic}...{/dynamic}</code> and be sure it will not be cached like the rest
-of the page.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>The above example shall just demonstrate how a dynamic block plugins
-works. See
-<a href="#cacheability.sections"><code>Cacheability of Template Section</code></a> on how to
-disable caching of a template section by the built-in
-<a href="#language.function.nocache"><code>{nocache}</code></a> and
-<a href="#language.function.nocache"><code>{/nocache}</code></a> tags.</p>

-<blockquote>
-<p><strong>Note</strong></p>
-<p>With the introduction of PHP5, <code>assignByRef()</code> is not necessary for
-most intents and purposes. <code>assignByRef()</code> is useful if you want a PHP
-array index value to be affected by its reassignment from a template.
-Assigned object properties behave this way by default.</p>

-<p><strong>Note</strong></p>
-<p>All class variables have magic setter/getter methods available.
-setter/getter methods are camelCaseFormat, unlike the variable itself.
-So for example, you can set and get the \$smarty->template_dir
-variable with \$smarty->setTemplateDir(\$dir) and \$dir =
-\$smarty->getTemplateDir() respectively.</p>
-<p><strong>Note</strong></p>
-<p>See
-<a href="../advanced-features/advanced-features-template-settings/"><code>Changing settings by template</code></a>
-section for how to change Smarty class variables for individual
-templates.</p>

-<h1 id="compile_check-variablecompilecheck">\$compile_check {#variable.compile.check}</h1>
-<p>Upon each invocation of the PHP application, Smarty tests to see if the
-current template has changed (different timestamp) since the last time
-it was compiled. If it has changed, it recompiles that template. If the
-template has yet not been compiled at all, it will compile regardless of
-this setting. By default this variable is set to TRUE.</p>
-<p>Once an application is put into production (ie the templates won\'t be
-changing), the compile check step is no longer needed. Be sure to set
-<code>$compile_check</code> to FALSE for maximum performance. Note that if you
-change this to FALSE and a template file is changed, you will *not*
-see the change since the template will not get recompiled.</p>
-<p>If <a href="#variable.caching"><code>$caching</code></a> is enabled and <code>$compile_check</code> is
-enabled, then the cache files will get regenerated if an involved
-template file or config file was updated.</p>
-<p>As of Smarty 3.1 <code>$compile_check</code> can be set to the value
-<code>\Smarty\Smarty::COMPILECHECK_CACHEMISS</code>. This enables Smarty to revalidate the
-compiled template, once a cache file is regenerated. So if there was a
-cached template, but it\'s expired, Smarty will run a single
-compile_check before regenerating the cache.</p>
-<p>See <a href="#variable.force.compile"><code>$force_compile</code></a> and
-<a href="#api.clear.compiled.tpl"><code>clearCompiledTemplate()</code></a>.</p>

-<h1 id="custom-cache-implementation-cachingcustom">Custom Cache Implementation {#caching.custom}</h1>
-<p>As an alternative to using the default file-based caching mechanism, you
-can specify a custom cache implementation that will be used to read,
-write and clear cached files.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>In Smarty2 this used to be a callback function called
-<code>$cache_handler_func</code>. Smarty3 replaced this callback by the
-<code>Smarty_CacheResource</code> module.</p>
-</blockquote>
-<p>With a custom cache implementation you\'re likely trying to achieve at
-least one of the following goals: replace the slow filesystem by a
-faster storage engine, centralize the cache to be accessible to multiple
-servers.</p>
-<p>Smarty allows CacheResource implementations to use one of the APIs
-<code>\Smarty\Cacheresource\Custom</code> or <code>\Smarty\Cacheresource\KeyValueStore</code>.
-<code>\Smarty\Cacheresource\Custom</code> is a simple API directing all read, write,
-clear calls to your implementation. This API allows you to store
-wherever and however you deem fit. The
-<code>\Smarty\Cacheresource\KeyValueStore</code> API allows you to turn any \"dumb\"
-KeyValue-Store (like APC, Memcache, ...) into a full-featured
-CacheResource implementation. That is, everything around deep
-cache-groups like \"a|b|c\" is being handled for you in way that
-allows clearing the cache-group \"a\" and all nested groups are cleared
-as well - even though KeyValue-Stores don\'t allow this kind of
-hierarchy by nature.</p>
-<p>Custom CacheResources may be put in a file <code>cacheresource.foobarxyz.php</code>
-within your <a href="#variable.plugins.dir"><code>$plugins_dir</code></a>, or registered on
-runtime with <a href="#api.register.cacheresource"><code>registerCacheResource()</code></a>.
-In either case you need to set <a href="#variable.caching.type"><code>$caching_type</code></a>
-to invoke your custom CacheResource implementation.</p>

-<h1 id="multiple-caches-per-page-cachingmultiplecaches">Multiple Caches Per Page {#caching.multiple.caches}</h1>
-<p>You can have multiple cache files for a single call to
-<a href="#api.display"><code>display()</code></a> or <a href="#api.fetch"><code>fetch()</code></a>. Let\'s say that
-a call to <code>display('index.tpl')</code> may have several different output
-contents depending on some condition, and you want separate caches for
-each one. You can do this by passing a <code>$cache_id</code> as the second
-parameter to the function call.</p>
-<div class="highlight"><pre><span></span><code>&lt;?php
-use Smarty\Smarty;
-$smarty = new Smarty;
-
-$smarty-&gt;setCaching(Smarty::CACHING_LIFETIME_CURRENT);
-
-$my_cache_id = $_GET[&#39;article_id&#39;];
-
-$smarty-&gt;display(&#39;index.tpl&#39;, $my_cache_id);
-?&gt;
-</code></pre></div>
-<p>Above, we are passing the variable <code>$my_cache_id</code> to
-<a href="#api.display"><code>display()</code></a> as the <code>$cache_id</code>. For each unique value of
-<code>$my_cache_id</code>, a separate cache will be generated for <code>index.tpl</code>. In
-this example, <code>article_id</code> was passed in the URL and is used as the
-<code>$cache_id</code>.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>Be very cautious when passing values from a client (web browser) into
-Smarty or any PHP application. Although the above example of using the
-article_id from the URL looks handy, it could have bad consequences.
-The <code>$cache_id</code> is used to create a directory on the file system, so
-if the user decided to pass an extremely large value for article_id,
-or write a script that sends random article_id\'s at a rapid pace,
-this could possibly cause problems at the server level. Be sure to
-sanitize any data passed in before using it. In this instance, maybe
-you know the article_id has a length of ten characters and is made up
-of alpha-numerics only, and must be a valid article_id in the
-database. Check for this!</p>
-</blockquote>
-<p>Be sure to pass the same <code>$cache_id</code> as the second parameter to
-<a href="#api.is.cached"><code>isCached()</code></a> and <a href="#api.clear.cache"><code>clearCache()</code></a>.</p>
-<div class="highlight"><pre><span></span><code>&lt;?php
-use Smarty\Smarty;
-$smarty = new Smarty;
-
-$smarty-&gt;setCaching(Smarty::CACHING_LIFETIME_CURRENT);
-
-$my_cache_id = $_GET[&#39;article_id&#39;];
-
-if(!$smarty-&gt;isCached(&#39;index.tpl&#39;,$my_cache_id)) {
-    // No cache available, do variable assignments here.
-    $contents = get_database_contents();
-    $smarty-&gt;assign($contents);
-}
-
-$smarty-&gt;display(&#39;index.tpl&#39;,$my_cache_id);
-?&gt;
-</code></pre></div>
-<p>You can clear all caches for a particular <code>$cache_id</code> by passing NULL as
-the first parameter to <a href="#api.clear.cache"><code>clearCache()</code></a>.</p>
-<div class="highlight"><pre><span></span><code>&lt;?php
-use Smarty\Smarty;
-$smarty = new Smarty;
-
-$smarty-&gt;setCaching(Smarty::CACHING_LIFETIME_CURRENT);
-
-// clear all caches with &quot;sports&quot; as the $cache_id
-$smarty-&gt;clearCache(null,&#39;sports&#39;);
-
-$smarty-&gt;display(&#39;index.tpl&#39;,&#39;sports&#39;);
-?&gt;
-</code></pre></div>
-<p>In this manner, you can "group" your caches together by giving them the
-same <code>$cache_id</code>.</p>

-<h1 id="how-plugins-work-pluginshowto">How Plugins Work {#plugins.howto}</h1>
-<p>Plugins are always loaded on demand. Only the specific modifiers,
-functions, resources, etc invoked in the templates scripts will be
-loaded. Moreover, each plugin is loaded only once, even if you have
-several different instances of Smarty running within the same request.</p>
-<p>Pre/postfilters and output filters are a bit of a special case. Since
-they are not mentioned in the templates, they must be registered or
-loaded explicitly via API functions before the template is processed.
-The order in which multiple filters of the same type are executed
-depends on the order in which they are registered or loaded.</p>
-<p>The <a href="#variable.plugins.dir">plugins directory</a> can be a string
-containing a path or an array containing multiple paths. To install a
-plugin, simply place it in one of the directories and Smarty will use it
-automatically.</p>

-<h1 id="naming-conventions-pluginsnamingconventions">Naming Conventions {#plugins.naming.conventions}</h1>
-<p>Plugin files and functions must follow a very specific naming convention
-in order to be located by Smarty.</p>
-<p><strong>plugin files</strong> must be named as follows:</p>
-<blockquote>
-<p><code>type.name.php</code></p>
-</blockquote>
-<ul>
-<li>
-<p>Where <code>type</code> is one of these plugin types:</p>
-<ul>
-<li>
-<p>function</p>
-</li>
-<li>
-<p>modifier</p>
-</li>
-<li>
-<p>block</p>
-</li>
-<li>
-<p>compiler</p>
-</li>
-<li>
-<p>prefilter</p>
-</li>
-<li>
-<p>postfilter</p>
-</li>
-<li>
-<p>outputfilter</p>
-</li>
-<li>
-<p>resource</p>
-</li>
-</ul>
-</li>
-<li>
-<p>And <code>name</code> should be a valid identifier; letters, numbers, and
-    underscores only, see <a href="https://www.php.net/language.variables">php
-    variables</a>.</p>
-</li>
-<li>
-<p>Some examples: <code>function.html_select_date.php</code>, <code>resource.db.php</code>,
-    <code>modifier.spacify.php</code>.</p>
-</li>
-</ul>
-<p><strong>plugin functions</strong> inside the PHP files must be named as follows:</p>
-<blockquote>
-<p><code>smarty_type_name</code></p>
-</blockquote>
-<ul>
-<li>
-<p>The meanings of <code>type</code> and <code>name</code> are the same as above.</p>
-</li>
-<li>
-<p>An example modifier name <code>foo</code> would be
-    <code>function smarty_modifier_foo()</code>.</p>
-</li>
-</ul>
-<p>Smarty will output appropriate error messages if the plugin file it
-needs is not found, or if the file or the plugin function are named
-improperly.</p>

-<p>Prefilter and postfilter plugins are very similar in concept; where they

-<p>Prefilters are used to process the source of the template immediately
-before compilation. The first parameter to the prefilter function is the
-template source, possibly modified by some other prefilters. The plugin
-is supposed to return the modified source. Note that this source is not
-saved anywhere, it is only used for compilation.</p>

-<p>name</p>

-<p>Postfilters are used to process the compiled output of the template (the
-PHP code) immediately after the compilation is done but before the
-compiled template is saved to the filesystem. The first parameter to the
-postfilter function is the compiled template code, possibly modified by
-other postfilters. The plugin is supposed to return the modified version

-<h1 id="resources-pluginsresources">Resources {#plugins.resources}</h1>
-<p>Resource plugins are meant as a generic way of providing template
-sources or PHP script components to Smarty. Some examples of resources:
-databases, LDAP, shared memory, sockets, and so on.</p>
-<p>Custom Resources may be put in a file <code>resource.foobarxyz.php</code> within
-your <a href="#variable.plugins.dir"><code>$plugins_dir</code></a>, or registered on runtime
-with <a href="#api.register.resource"><code>registerResource()</code></a>. In either case you
-will be able to access that resource by prepending its name to the
-template you\'re addressing: <code>foobarxyz:yourtemplate.tpl</code>.</p>
-<p>If a Resource\'s templates should not be run through the Smarty
-compiler, the Custom Resource may extend <code>\Smarty\Resource\UncompiledPlugin</code>.
-The Resource Handler must then implement the function
-<code>renderUncompiled(\Smarty\Template $_template)</code>. <code>$_template</code> is
-a reference to the current template and contains all assigned variables
-which the implementor can access via
-<code>$_template-&gt;getSmarty()-&gt;getTemplateVars()</code>. These Resources simply echo
-their rendered content to the output stream. The rendered output will be
-output-cached if the Smarty instance was configured accordingly. See
-<code>src/Resource/PhpPlugin.php</code> for an example.</p>
-<p>If the Resource\'s compiled templates should not be cached on disk, the
-Custom Resource may extend <code>\Smarty\Resource\RecompiledPlugin</code>. These Resources
-are compiled every time they are accessed. This may be an expensive
-overhead. See <code>src/Resource/StringEval.php</code> for an
-example.</p>

-<h1 id="writing-plugins-pluginswriting">Writing Plugins {#plugins.writing}</h1>
-<p>Plugins can be either loaded by Smarty automatically from the filesystem
-or they can be registered at runtime via one of the register_* API
-functions. They can also be unregistered by using unregister_* API
-functions.</p>
-<p>For the plugins that are registered at runtime, the name of the plugin
-function(s) does not have to follow the naming convention.</p>
-<p>As a general rule, the currently evaluated template\'s
-Smarty_Internal_Template object is always passed to the plugins as the
-last parameter with two exceptions:</p>
-<ul>
-<li>
-<p>modifiers do not get passed the Smarty_Internal_Template object at
-    all</p>
-</li>
-<li>
-<p>blocks get passed <code>$repeat</code> after the Smarty_Internal_Template
-    object to keep backwards compatibility to older versions of Smarty.</p>
-</li>
-</ul>

-<h1 id="custom-template-resources-resourcescustom">Custom Template Resources {#resources.custom}</h1>
-<p>You can retrieve templates using whatever possible source you can access
-with PHP: databases, sockets, files, etc. You do this by writing
-resource plugin functions and registering them with Smarty.</p>
-<p>See <a href="#plugins.resources">resource plugins</a> section for more information
-on the functions you are supposed to provide.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>Note that you cannot override the built-in <code>file:</code> resource, but you
-can provide a resource that fetches templates from the file system in
-some other way by registering under another resource name.</p>

-<h1 id="extends-template-resources-resourcesextends">Extends Template Resources {#resources.extends}</h1>
-<p>The <code>extends:</code> resource is used to define child/parent relationships for
-template inheritance from the PHP script. For details see section of
-<a href="#advanced.features.template.inheritance">Template Inheritance</a>.</p>
-<p>As of Smarty 3.1 the <code>extends:</code> resource may use any available <a href="#resources">template
-resource</a>, including <code>string:</code> and <code>eval:</code>. When <a href="#resources.string">templates
-from strings</a> are used, make sure they are properly
-(url or base64) encoded. Is an <code>eval:</code> resource found within an
-inheritance chain, its \"don\'t save a compile file\" property is
-superseded by the <code>extends:</code> resource. The templates within an
-inheritance chain are not compiled separately, though. Only a single
-compiled template will be generated.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>Use this when inheritance is required programmatically. When inheriting
-within PHP, it is not obvious from the child template what inheritance
-took place. If you have a choice, it is normally more flexible and
-intuitive to handle inheritance chains from within the templates.</p>
-</blockquote>
-<div class="highlight"><pre><span></span><code>&lt;?php
-$smarty-&gt;display(&#39;extends:parent.tpl|child.tpl|grandchild.tpl&#39;);

-<h1 id="stream-template-resources-resourcesstreams">Stream Template Resources {#resources.streams}</h1>
-<p>Streams allow you to use PHP streams as a template resource. The syntax
-is much the same a traditional template resource names.</p>
-<p>Smarty will first look for a registered template resource. If nothing is
-found, it will check if a PHP stream is available. If a stream is
-available, Smarty will use it to fetch the template.</p>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>You can further define allowed streams with security enabled.</p>
-</blockquote>
-<p>Using a PHP stream for a template resource from the display() function.</p>
-<div class="highlight"><pre><span></span><code> $smarty-&gt;display(&#39;foo:bar.tpl&#39;);
-</code></pre></div>
-<p>Using a PHP stream for a template resource from within a template.</p>

-<h1 id="string-template-resources-resourcesstring">String Template Resources {#resources.string}</h1>
-<p>Smarty can render templates from a string by using the <code>string:</code> or
-<code>eval:</code> resource.</p>
-<ul>
-<li>
-<p>The <code>string:</code> resource behaves much the same as a template file. The
-    template source is compiled from a string and stores the compiled
-    template code for later reuse. Each unique template string will
-    create a new compiled template file. If your template strings are
-    accessed frequently, this is a good choice. If you have frequently
-    changing template strings (or strings with low reuse value), the
-    <code>eval:</code> resource may be a better choice, as it doesn\'t save
-    compiled templates to disk.</p>
-</li>
-<li>
-<p>The <code>eval:</code> resource evaluates the template source every time a page
-    is rendered. This is a good choice for strings with low reuse value.
-    If the same string is accessed frequently, the <code>string:</code> resource
-    may be a better choice.</p>
-</li>
-</ul>
-<blockquote>
-<p><strong>Note</strong></p>
-<p>With a <code>string:</code> resource type, each unique string generates a
-compiled file. Smarty cannot detect a string that has changed, and
-therefore will generate a new compiled file for each unique string. It
-is important to choose the correct resource so that you do not fill
-your disk space with wasted compiled strings.</p>
-</blockquote>

-<p>Both <code>string:</code> and <code>eval:</code> resources may be encoded with
-<a href="https://www.php.net/urlencode"><code>urlencode()</code></a> or
-<a href="https://www.php.net/urlencode"><code>base64_encode()</code></a>. This is not necessary

Things such as     including other templates,     alternating table row colors,     upper-casing a variable,     looping over an array of data and     rendering it are examples of presentation logic.</li> <li>This does not mean however that Smarty forces a separation of     business and presentation logic. Smarty has no knowledge of which is     which, so placing business logic in the template is your own doing.</li> <li>Also, if you desire no logic in your templates you certainly can     do so by boiling the content down to text and variables only.</li> </ul>"},{"location":"features/#how-does-it-work","title":"How does it work?","text":"<p>Under the hood, Smarty \"compiles\" (basically copies and converts) the templates into PHP scripts. This happens once when each template is first invoked, and then the compiled versions are used from that point forward. Smarty takes care of this for you, so the template designer just edits the Smarty templates and never has to manage the compiled versions. This approach keeps the templates easy to maintain, and yet keeps execution times extremely fast since the compiled code is just PHP. And of course, all PHP scripts take advantage of PHP op-code caches such as APC.</p>"},{"location":"features/#template-inheritance","title":"Template Inheritance","text":"<p>Template inheritance was introduced in Smarty 3. Before template inheritance, we managed our templates in pieces such as header and footer templates. This organization lends itself to many problems that require some hoop-jumping, such as managing content within the header/footer on a per-page basis. With template inheritance, instead of including other templates we maintain our templates as single pages. We can then manipulate blocks of content within by inheriting them. This makes templates intuitive, efficient and easy to manage. See Template Inheritance for more info.</p>"},{"location":"features/#why-not-use-xmlxslt-syntax","title":"Why not use XML/XSLT syntax?","text":"<p>There are a couple of good reasons. First, Smarty can be used for more than just XML/HTML based templates, such as generating emails, javascript, CSV, and PDF documents. Second, XML/XSLT syntax is even more verbose and fragile than PHP code! It is perfect for computers, but horrible for humans. Smarty is about being easy to read, understand and maintain.</p>"},{"location":"features/#template-security","title":"Template Security","text":"<p>Although Smarty insulates you from PHP, you still have the option to use it in certain ways if you wish. Template security forces the restriction of PHP (and select Smarty functions.) This is useful if you have third parties editing templates, and you don't want to unleash the full power of PHP or Smarty to them.</p>"},{"location":"features/#integration","title":"Integration","text":"<p>Sometimes Smarty gets compared to Model-View-Controller (MVC) frameworks. Smarty is not an MVC, it is just the presentation layer, much like the View (V) part of an MVC. As a matter of fact, Smarty can easily be integrated as the view layer of an MVC. Many of the more popular ones have integration instructions for Smarty, or you may find some help here in the forums and documentation.</p>"},{"location":"features/#other-template-engines","title":"Other Template Engines","text":"<p>Smarty is not the only engine following the \"Separate Programming Code from Presentation\" philosophy. For instance, Python has template engines built around the same principles such as Django Templates and CheetahTemplate. Note: Languages such as Python do not mix with HTML natively, which give them the advantage of proper programming code separation from the outset. There are libraries available to mix Python with HTML, but they are typically avoided.</p>"},{"location":"features/#what-smarty-is-not","title":"What Smarty is Not","text":"<p>Smarty is not an application development framework. Smarty is not an MVC. Smarty is not an alternative to Laravel, Symfony, CodeIgniter, or any of the other application development frameworks for PHP.</p> <p>Smarty is a template engine, and works as the (V)iew component of your application. Smarty can easily be coupled to any of the engines listed above as the view component. No different than any other software, Smarty has a learning curve. Smarty does not guarantee good application design or proper separation of presentation, this still needs to be addressed by a competent developer and web designer.</p>"},{"location":"features/#is-smarty-right-for-me","title":"Is Smarty Right for Me?","text":"<p>Smarty is not meant to be a tool for every job.

For OS X users, the default is user \"www\" and group \"www\". If you are using Apache, you can look in your <code>httpd.conf</code> file to see what user and group are being used.</p> <pre><code>chown nobody:nobody /web/www.example.com/guestbook/templates_c/\nchmod 770 /web/www.example.com/guestbook/templates_c/\n\nchown nobody:nobody /web/www.example.com/guestbook/cache/\nchmod 770 /web/www.example.com/guestbook/cache/\n</code></pre> <p>You can verify if your system has the correct access rights for     these directories with <code>testInstall()</code>:</p> <pre><code>&lt;?php\nuse Smarty\\Smarty;\n$smarty = new Smarty();\n$smarty-&gt;setTemplateDir('/some/template/dir');\n$smarty-&gt;setConfigDir('/some/config/dir');\n$smarty-&gt;setCompileDir('/some/compile/dir');\n$smarty-&gt;setCacheDir('/some/cache/dir');\n$smarty-&gt;testInstall();\n</code></pre> <p>Now, let's create the <code>index.tpl</code> file that Smarty will display. This needs to be located in the <code>$template_dir</code>.</p> <pre><code>{* Smarty *}\nHello {$name}, welcome to Smarty!\n</code></pre> <p>Note</p> <p><code>{* Smarty *}</code> is a template comment. It is not required, but it is good practice to start all your template files with this comment. It makes the file easy to recognize regardless of the file extension. For example, text editors could recognize the file and turn on special syntax highlighting.</p> <p>Now lets edit our php file. We'll create an instance of Smarty, <code>assign()</code> a template variable and <code>display()</code> the <code>index.tpl</code> file.</p> <pre><code>&lt;?php\nrequire 'vendor/autoload.php';\nuse Smarty\\Smarty;\n$smarty = new Smarty();\n$smarty-&gt;setTemplateDir('/web/www.example.com/guestbook/templates/');\n$smarty-&gt;setCompileDir('/web/www.example.com/guestbook/templates_c/');\n$smarty-&gt;setConfigDir('/web/www.example.com/guestbook/configs/');\n$smarty-&gt;setCacheDir('/web/www.example.com/guestbook/cache/');\n$smarty-&gt;assign('name', 'Ned');\n$smarty-&gt;display('index.tpl');\n</code></pre> <p>Note</p> <p>In our example, we are setting absolute paths to all the Smarty directories. If <code>/web/www.example.com/guestbook/</code> is within your PHP include_path, then these settings are not necessary. However, it is more efficient and (from experience) less error-prone to set them to absolute paths.

The issue isn't their ability to learn PHP, it is about the consequences of mixing PHP with HTML. If designers use PHP, it is too easy to add code into templates that doesn't belong there (you just handed them a swiss-army knife when they just needed a knife.) You can teach them the rules of application design, but this is probably something they don't really need to learn (now they are developers!) The PHP manual is also an overwhelming pile of information to sift through. It is like handing the owner of a car the factory assembly manual when all they need is the owners manual. Smarty gives web designers exactly the tools they need, and gives developers fine-grained control over those tools.

In either case you need to set <code>$caching_type</code> to invoke your custom CacheResource implementation.</p> <pre><code>&lt;?php\n\nuse Smarty\\Smarty;\n$smarty = new Smarty();\n$smarty-&gt;caching_type = 'mysql';\n\n/**\n * MySQL CacheResource\n *\n * CacheResource Implementation based on the Custom API to use\n * MySQL as the storage resource for Smarty's output caching.\n *\n * Table definition:\n * &lt;pre&gt;CREATE TABLE IF NOT EXISTS `output_cache` (\n *   `id` CHAR(40) NOT NULL COMMENT 'sha1 hash',\n *   `name` VARCHAR(250) NOT NULL,\n *   `cache_id` VARCHAR(250) NULL DEFAULT NULL,\n *   `compile_id` VARCHAR(250) NULL DEFAULT NULL,\n *   `modified` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,\n *   `content` LONGTEXT NOT NULL,\n *   PRIMARY KEY (`id`),\n *   INDEX(`name`),\n *   INDEX(`cache_id`),\n *   INDEX(`compile_id`),\n *   INDEX(`modified`)\n * ) ENGINE = InnoDB;&lt;/pre&gt;\n *\n\n * @author Rodney Rehm\n */\nclass My_CacheResource_Mysql extends \\Smarty\\Cacheresource\\Custom {\n    // PDO instance\n    protected $db;\n    protected $fetch;\n    protected $fetchTimestamp;\n    protected $save;\n\n    public function __construct() {\n        try {\n            $this-&gt;db = new PDO(\"mysql:dbname=test;host=127.0.0.1\", \"smarty\", \"smarty\");\n        } catch (PDOException $e) {\n            throw new \\Smarty\\Exception('Mysql Resource failed: ' . $e-&gt;getMessage());\n        }\n        $this-&gt;fetch = $this-&gt;db-&gt;prepare('SELECT modified, content FROM output_cache WHERE id = :id');\n        $this-&gt;fetchTimestamp = $this-&gt;db-&gt;prepare('SELECT modified FROM output_cache WHERE id = :id');\n        $this-&gt;save = $this-&gt;db-&gt;prepare('REPLACE INTO output_cache (id, name, cache_id, compile_id, content)\n            VALUES  (:id, :name, :cache_id, :compile_id, :content)');\n    }\n\n    /**\n     * fetch cached content and its modification time from data source\n     *\n     * @param string $id unique cache content identifier\n     * @param string $name template name\n     * @param string $cache_id cache id\n     * @param string $compile_id compile id\n     * @param string $content cached content\n     * @param integer $mtime cache modification timestamp (epoch)\n     * @return void\n     */\n    protected function fetch($id, $name, $cache_id, $compile_id, &amp;$content, &amp;$mtime)\n    {\n        $this-&gt;fetch-&gt;execute(array('id' =&gt; $id));\n        $row = $this-&gt;fetch-&gt;fetch();\n        $this-&gt;fetch-&gt;closeCursor();        \n        if ($row) {\n            $content = $row['content'];\n            $mtime = strtotime($row['modified']);\n        } else {\n            $content = null;\n            $mtime = null;\n        }\n    }\n\n    /**\n     * Fetch cached content's modification timestamp from data source\n     *\n     * @note implementing this method is optional.

Before template inheritance, we managed our templates in pieces such as header and footer templates. This organization lends itself to many problems that require some hoop-jumping, such as managing content within the header/footer on a per-page basis. With template inheritance, instead of including other templates we maintain our templates as single pages. We can then manipulate blocks of content within by inheriting them. This makes templates intuitive, efficient and easy to manage. See Template Inheritance for more info.</p>"},{"location":"features/#why-not-use-xmlxslt-syntax","title":"Why not use XML/XSLT syntax?","text":"<p>There are a couple of good reasons.

This change does not     affect the template designer, the content will still arrive in the     template exactly the same.</p> </li> <li> <p>Likewise, if the template designer wants to completely redesign the     templates, this would require no change to the application logic.</p> </li> <li> <p>Therefore, the programmer can make changes to the application logic     without the need to restructure templates, and the template designer     can make changes to templates without breaking application logic.</p> </li> </ul>"},{"location":"philosophy/#goals","title":"Goals","text":"<p>The Smarty design was largely driven by these goals: -   clean separation of presentation from application code -   PHP backend, Smarty template frontend -   complement PHP, not replace it -   fast development/deployment for programmers and designers -   quick and easy to maintain -   syntax easy to understand, no PHP knowledge necessary -   flexibility for custom development -   security: insulation from PHP -   free, open source</p>"},{"location":"philosophy/#two-camps-of-thought","title":"Two camps of thought","text":"<p>When it comes to templating in PHP, there are basically two camps of thought.

Although this approach is fastest from a pure script-execution point of view, many would argue that the PHP syntax is messy and complicated when mixed with tagged markup such as HTML.</p> <p>The second camp exclaims that presentation should be void of all programming code, and instead use simple tags to indicate where application content is revealed. This approach is common with other template engines (even in other programming languages), and is also the approach that Smarty takes.

PHP syntax works well for application code, but quickly degenerates     when mixed with HTML. Smarty\\'s simple {tag} syntax is designed     specifically to express presentation. Smarty focuses your templates     on presentation and less on \\\"code\\\". This lends to quicker template     deployment and easier maintenance. Smarty syntax requires no working     knowledge of PHP, and is intuitive for programmers and     non-programmers alike.</p> </li> <li> <p>INSULATION: When PHP is mixed with templates, there are no     restrictions on what type of logic can be injected into a template.     Smarty insulates the templates from PHP, creating a controlled     separation of presentation from business logic. Smarty also has     security features that can further enforce restrictions on     templates.</p> </li> </ul>"},{"location":"philosophy/#web-designers-and-php","title":"Web designers and PHP","text":"<p>A common question: \"Web designers have to learn a syntax anyway, why not PHP?\" Of course web designers can learn PHP, and they may already be familiar with it. The issue isn't their ability to learn PHP, it is about the consequences of mixing PHP with HTML. If designers use PHP, it is too easy to add code into templates that doesn't belong there (you just handed them a swiss-army knife when they just needed a knife.) You can teach them the rules of application design, but this is probably something they don't really need to learn (now they are developers!) The PHP manual is also an overwhelming pile of information to sift through. It is like handing the owner of a car the factory assembly manual when all they need is the owners manual. Smarty gives web designers exactly the tools they need, and gives developers fine-grained control over those tools. The simplicity of the tag-based syntax is also a huge welcome for designers, it helps them streamline the organization and management of templates.</p>"},{"location":"api/basics/","title":"Basics","text":""},{"location":"api/basics/#installation","title":"Installation","text":"<p>For installation instructies, please see the getting started section.</p>"},{"location":"api/basics/#rendering-a-template","title":"Rendering a template","text":"<p>Here's how you create an instance of Smarty in your PHP scripts: <pre><code>&lt;?php\nrequire 'vendor/autoload.php';\nuse Smarty\\Smarty;\n$smarty = new Smarty();\n</code></pre></p> <p>You now have a Smarty object that you can use to render templates.</p> <pre><code>&lt;?php\nrequire 'vendor/autoload.php';\nuse Smarty\\Smarty;\n$smarty = new Smarty();\n$smarty-&gt;display('string:The current smarty version is: {$smarty.version}.');\n// or \necho $smarty-&gt;fetch('string:The current smarty version is: {$smarty.version}.');\n</code></pre>"},{"location":"api/basics/#using-file-based-templates","title":"Using file-based templates","text":"<p>You probably want to manage your templates as files.

Section names can be arbitrary strings not containing <code>[</code> or <code>]</code> symbols. The four variables at the top are global variables, or variables not within a section. These variables are always loaded from the config file. If a particular section is loaded, then the global variables and the variables from that section are also loaded.
