The document discusses the Smarty template engine. It explains that Smarty separates logic from presentation, allowing for reduced overhead in templating. Smarty is described as the view component of an application and is not a full application framework or MVC framework itself. Examples are provided of common Smarty syntax like {assign}, {section}, {foreach}, and conditionals like {if} to manipulate and display template variables.
![{section}
index.php
$sangam = array(“prabha”,”lakshmi”);
$smarty->assign(“sangam”,$sangam);
index.tpl
{section name=member loop=$sangam}
{$sangam[member]}
{/section}](https://image.slidesharecdn.com/smarty-120514111653-phpapp02/85/Smarty-6-320.jpg)

- 6. {section} index.php $sangam = array(“prabha”,”lakshmi”); $smarty->assign(“sangam”,$sangam); index.tpl {section name=member loop=$sangam} {$sangam[member]} {/section}
- 7. {foreach} index.php $arr = array(9 => 'Tennis', 3 => 'Swimming', 8 => 'Coding'); $smarty->assign('myArray', $arr); index.tpl <ul> {foreach from=$myArray key=k item=v} <li> {$k}: {$v} </li> {/foreach} </ul>
- 8. {foreach} index.php $arr = array(9 => 'Tennis', 3 => 'Swimming', 8 => 'Coding'); $smarty->assign('myArray', $arr); index.tpl <ul> {foreach from=$myArray key=k item=v} <li> {$k}: {$v} </li> {/foreach} </ul> <ul> <li>9: Tennis</li> <li>3: Swimming</li> <li>8: Coding</li> </ul>
- 9. {foreach} index.php $smarty->assign(‘efforts', array( array( ‘dev' => '1', ‘mnt' => '2', ‘qa' => '3'), array( ‘dev' => ‘4', ‘mnt' => ‘5', ‘qa' => ‘6') ));
- 10. {foreach} index.php $smarty->assign(‘efforts', array( array( ‘dev' => '1', ‘mnt' => '2', ‘qa' => '3'), array( ‘dev' => ‘4', ‘mnt' => ‘5', ‘qa' => ‘6') )); {foreach name=outer item=effort from=$efforts} {foreach key=key item=item from=$effort} {$key}: {$item} <br/> {/foreach} {/foreach}

- 13. {capture} {capture name=banner} {include file='get_banner.tpl'} {/capture} {if $smarty.capture.banner ne ''} <div id="banner"> {$smarty.capture.banner} </div> {/if}
- 14. {literal} {literal} <script type="text/javascript"> alert(“Hello World!”); </script> {/literal} {literal} <style type="text/css"> .container{ display:none; } </style> {/literal}
- 15. {php} {php} global $foo, $bar; if($foo == $bar){ echo 'This will be sent to browser'; } $this->assign(‘flavor',‘Chocolate'); {/php} {$flavor} is my fav ice cream :-)
