Part 7: Create your own Login System using PHP and MySql

7. Creating the Logout Script

Creating the logout script is straightforward. All you need to do is destroy the sessions that were declared in the authenticate file.

Edit the logout.php file and add the following code:

<?php
session_start();
session_destroy();
// Redirect to the login page:
header('Location: index.html');
?>

Initialize sessions, destroy them, and redirect the user to the login page. We use sessions to determine whether the user is logged in or not, so by removing them, the user will not be logged in.
