compile\_id
This returns the template output instead of [displaying](#api.display)
it. Supply a valid [template resource](#resources) type and path. As an
optional second parameter, you can pass a `$cache id`, see the [caching
section](#caching) for more information.
PARAMETER.COMPILEID
<?php
include('Smarty.class.php');
$smarty = new Smarty;
$smarty->setCaching(true);
// set a separate cache_id for each unique URL
$cache_id = md5($_SERVER['REQUEST_URI']);
// capture the output
$output = $smarty->fetch('index.tpl', $cache_id);
// do something with $output here
echo $output;

List master
{textformat wrap=40}
This is some long-winded disclaimer text that would automatically get wrapped
at 40 characters. This helps make the text easier to read in mail programs that
do not wrap sentences for you.
{/textformat}
The php script using the PHP [`mail()`](&url.php-manual;function.mail)
function
<?php
// get $contact_info from db or other resource here
$smarty->assign('contact_info',$contact_info);
$smarty->assign('login_url',"http://{$_SERVER['SERVER_NAME']}/login");
mail($contact_info['email'], 'Thank You', $smarty->fetch('email_body.tpl'));
?>
