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 />
