I\'m currently working on a mobile site with authentication using PHP sessions with a database. I have a login page with a form that goes to server_login.php
I got a solution for you, Why dont you rather use Explode if your url is something like
Url-> website.com/test/blog.php
$StringExplo=explode("/",$_SERVER['REQUEST_URI']); $HeadTo=$StringExplo[0]."/Index.php"; Header("Location: ".$HeadTo);
