How to skip page in PHP when user logs out

Question

I want to end my previous page when the end user clicks the LogOut or Back button of the browser.

Answer 1

If you enable this at the top of all your pages, this will require the client to always reload the content, forcing the back button to request a new copy of the page.

<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>

Destroy the session key with session_destroy();
