PHP Switch Case Url's

[itsoisi]

We currently use Switch case url config to help us with the navigation on some of our urls, Im not sure if there is an easier way to do it but i couldnt seem to find 1.\[code\]<?php if (! isset($_GET['step'])) { include('./step1.php'); } else { $page = $_GET['step']; switch($page) { case '1': include('./step1.php'); break; case '2': include('./step2.php'); break; } } ?>\[/code\]Now this system works perfectly but the only snag we hit is if they type in xxxxxx.php?step=3 boom they just get a blank page and that should be correct as there is no case for it to handle '3' but what i was wondering is .. is there any php code i could add to the bottom that may tell it for any case other than those 2 to redirect it back to xxxxx.php ?
