DevShed has posted a new tutorial today about building another common component of a website - the logout component.

The main function of the logout class is to log out a user and then redirect the user to the login page. On a programmatic level, the logout class terminates and destroys the session variables that the login class created for the user and also logs the exit time to the database. This article will show you how to create a logout class. It is part of a series on application framework components.

They build out the simple part of the class first, handling the variables and all and then move on to handling the logout and updating the database to reflect the user's status. They finish the tutorial off by giving both the database structure for the component and an example of it in action.
