Variables assigned from PHP {#language.assigned.variables}
===========================

Assigned variables that are referenced by preceding them with a dollar
(`$`) sign.

PHP code


    <?php

    $smarty = new Smarty();

    $smarty->assign('firstname', 'Doug');
    $smarty->assign('lastname', 'Evans');
    $smarty->assign('meetingPlace', 'New York');

    $smarty->display('index.tpl');

    ?>

`index.tpl` source:


    Hello {$firstname} {$lastname}, glad to see you can make it.
    <br />
    {* this will not work as $variables are case sensitive *}
    This weeks meeting is in {$meetingplace}.
    {* this will work *}
    This weeks meeting is in {$meetingPlace}.

       

This above would output:


    Hello Doug Evans, glad to see you can make it.
    <br />
    This weeks meeting is in .
    This weeks meeting is in New York.

      

Associative arrays {#language.variables.assoc.arrays}
------------------

You can also reference associative array variables by specifying the key
after a dot \".\" symbol.


    <?php
    $smarty->assign('Contacts',
        array('fax' => '555-222-9876',
              'email' => 'zaphod@slartibartfast.example.com',
              'phone' => array('home' => '555-444-3333',
                               'cell' => '555-111-1234')
                               )
             );
    $smarty->display('index.tpl');
    ?>

       

`index.tpl` source:


    {$Contacts.fax}<br />
    {$Contacts.email}<br />
    {* you can print arrays of arrays as well *}
    {$Contacts.phone.home}<br />
    {$Contacts.phone.cell}<br />

       

this will output:


    555-222-9876<br />
    zaphod@slartibartfast.example.com<br />
    555-444-3333<br />
    555-111-1234<br />

       

Array indexes {#language.variables.array.indexes}
-------------

You can reference arrays by their index, much like native PHP syntax.


    <?php
    $smarty->assign('Contacts', array(
                               '555-222-9876',
                               'zaphod@slartibartfast.example.com',
                                array('555-444-3333',
                                      '555-111-1234')
                                ));
    $smarty->display('index.tpl');
    ?>

       

`index.tpl` source:


    {$Contacts[0]}<br />
    {$Contacts[1]}<br />
    {* you can print arrays of arrays as well *}
    {$Contacts[2][0]}<br />
    {$Contacts[2][1]}<br />

       

This will output:


    555-222-9876<br />
    zaphod@slartibartfast.example.com<br />
    555-444-3333<br />
    555-111-1234<br />

       

Objects {#language.variables.objects}
-------

Properties of [objects](#advanced.features.objects) assigned from PHP
can be referenced by specifying the property name after the `->` symbol.


    name:  {$person->name}<br />
    email: {$person->email}<br />

       

this will output:


    name:  Zaphod Beeblebrox<br />
    email: zaphod@slartibartfast.example.com<br />
