# Variables assigned from PHP
2023-02-06 14:42:31 +01:00
Variables assigned from PHP are referenced by preceding them with a dollar
(`$`) sign.
2023-02-06 14:42:31 +01:00
## Examples
2023-02-06 14:42:31 +01:00
```php
<?php
use Smarty\Smarty;
2023-02-06 14:42:31 +01:00
$smarty = new Smarty();
2023-02-06 14:42:31 +01:00
$smarty->assign('firstname', 'Doug');
$smarty->assign('lastname', 'Evans');
$smarty->assign('meetingPlace', 'New York');
2023-02-06 14:42:31 +01:00
$smarty->display('index.tpl');
2023-02-06 14:42:31 +01:00
```
`index.tpl` source:
2023-02-06 14:42:31 +01:00
```smarty
Hello {$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:
2023-02-06 14:42:31 +01:00
```html
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
You can also reference associative array variables by specifying the key
2023-02-06 14:42:31 +01:00
after a dot "." symbol.
```php
<?php
$smarty->assign('Contacts',
array('fax' => '555-222-9876',
'email' => 'zaphod@slartibartfast.example.com',
'phone' => array('home' => '555-444-3333',
'cell' => '555-111-1234')
)
);
$smarty->display('index.tpl');
```
`index.tpl` source:
2023-02-06 14:42:31 +01:00
```smarty
{$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:
2023-02-06 14:42:31 +01:00
```html
555-222-9876<br />
zaphod@slartibartfast.example.com<br />
555-444-3333<br />
555-111-1234<br />
```

## Array indexes
You can reference arrays by their index, much like native PHP syntax.
2023-02-06 14:42:31 +01:00
```php
<?php
$smarty->assign('Contacts', array(
'555-222-9876',
'zaphod@slartibartfast.example.com',
array('555-444-3333',
'555-111-1234')
));
$smarty->display('index.tpl');
```
`index.tpl` source:
2023-02-06 14:42:31 +01:00
```smarty
{$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:
2023-02-06 14:42:31 +01:00
```html
555-222-9876<br />
zaphod@slartibartfast.example.com<br />
555-444-3333<br />
555-111-1234<br />
```

## Objects
2023-02-06 14:42:31 +01:00
Properties of [objects](../../programmers/advanced-features/advanced-features-objects.md) assigned from PHP
can be referenced by specifying the property name after the `->` symbol.
2023-02-06 14:42:31 +01:00
```smarty
name: {$person->name}<br />
email: {$person->email}<br />
```
this will output:
2023-02-06 14:42:31 +01:00
```html
name: Zaphod Beeblebrox<br />
email: zaphod@slartibartfast.example.com<br />
```
