<body>
<h2 style="text-decoration: underline;">rawurlencode()</h2>
<?php
$url = "http://ykyuen.wordpress.com/2009/10/11/密舒的BB/";
print "<p>".rawurlencode($url)."</p>";
?>
<br/>
<h2 style="text-decoration: underline;">rawurldecode()</h2>
<?php
$url = rawurlencode($url);
print "<p>".rawurldecode($url)."</p>";
?>
</body>
