logout button on the admin panel

The log-out button in the upper right corner of the admin panel needs to have something like the following features:

log-out
redirection tho the log-in page

Thanks :)

Start by locating the admin panel's upper-right logout button and the login page in the PHP application. Trace how the button currently behaves, then verify that logging out ends the session and redirects to the login page. Done means both logout and redirection work from the admin panel.
