Logging Out of a Session in PHP
An authorized user should have the ability to become unauthorized, that is, to perform a logout from their account. To do this, you need to create a separate page and remove the authorization mark on it, approximately like this:
<?php
session_start();
$_SESSION['auth'] = null;
?>
Implement the page logout.php. Upon visiting
it, the user should no longer be
authorized.
Modify the previous task so that the
page logout.php, after executing
its code, performs a redirect to index.php.
Show a message on that page stating
that the user is no longer authorized.
