A Login System for a PHP Email Application - The code: logging out and registration

(Page 3 of 4 )

Logout page. This page basically logs you out of the system and destroys any sessions that were created when you logged in. The application then returns the user to the login page.

Logout.php

<?
ob_start();
session_start();
session_unset();
session_destroy();
header("location:login.php");
?>

register.php. This code registers a new user. The fields provided in the form match those declared in the users table. See the previous article.

form
