title: Request string without GET arguments
body: <p>Is there a simple way to get the requested file or directory without the GET arguments? For example, if the URL is <code>http://example.com/directory/file.php?paramater=value</code> I would like to return just <code>http://example.com/directory/file.php</code>. I was surprised that there is not a simple index in <code>$_SERVER[]</code>. Did I miss one?</p>
