When a user click 'logout' i want it to run a script that clears the session but also in that script i want it to bring them back to the page they clicked the link on, how can I do this in php?

Thanks

<?php
//in a very simple way
session_start();
session_destroy();
header("location: //page they just came from");

?>
[/code]

yes but how would i dynamically know where they just came from - as logout option which runs this script will appear on many different locations.

Just use $_SERVER['HTTP_REFERER'] this should hold the full url to the page the user used in in order to get to your logout page.
So if you clicked a link in a page called page1.php in mydomain.com/folder1/page1.php then it should return mydomain.com/folder1/page1.php

However this variable can be spoofed and some browsers may not send this type of information over.
