<title>Example of a Template Cache Handling Function</title>
<para>
Create a function in your application that Smarty will use as a
cache handler. Set the name of it in the $cache_handler_func class
variable. Smarty will now use this to handle cached data. The first
argument is the action, which will be one of 'read', 'write' and
'clear'. The second parameter is the smarty object. The third
parameter is the cached content. Upon a write, Smarty passed th
cached content in this paramters. Upon a 'read', Smarty expects
your function to pass this by reference and populate it with the
cached data. Upon a 'clear', pass a dummy variable here since it is
not used. The fourth parameter is the name of the template file
(needed for read/write), the fifth parameter is the cache_id
(optional), and the sixth is the compile_id (optional)

<para>
<emphasis>foreach</emphasis> loops are an alternative to
<emphasis>section</emphasis> loops. <emphasis>foreach</emphasis> is
used to loop over a single associative array. The syntax for
<emphasis>foreach</emphasis> is much easier than
<emphasis>section</emphasis>, but as a tradeoff it can only be used
for a single array. <emphasis>foreach</emphasis> tags must be
paired with <emphasis>/foreach</emphasis> tags. Required parameters
are <emphasis>from</emphasis> and <emphasis>item</emphasis>. The
name of the foreach loop can be anything you like, made up of
letters, numbers and underscores. <emphasis>foreach</emphasis>
loops can be nested, and the nested foreach names must be unique
from each other. The <emphasis>from</emphasis> variable (usually an
array of values) determines the number of times
<emphasis>foreach</emphasis> will loop.
<emphasis>foreachelse</emphasis> is executed when there are no
values in the <emphasis>from</emphasis> variable.
