介绍PHP5的给类型函数应用

<?php
// Figure out our time format  If none is provided, default
// to RFC 2822 format:
$format = isset($_GET['format']) ? $_GET['format'] : 'r';

// Generate the date:
date_default_timezone_set('America/New_York');
$dstr = date($format);

// Define that we are returning XML content & not to cache:
header('Content-Type: text/xml');
header('Cache-control: no-cache');

// Now output a valid XML file:
echo <<<EOXML
<?xml version="1.0" ?>
<result>{$dstr}</result>
EOXML;
?>
