Learn how to log out users by removing their stored user authorization so that they must re-authenticate to regain acess.
- [Voiceover] Now that we've learned…how to authenticate a user and how to have pages…that require that authorization,…we need to learn how to remove the authorization…or to logout a user.…We already have a placeholder page for logging out,…logout.php, and we even have a link for it…at the top of our page,…but if we click that, it doesn't actually log us out.…We stay logged in because it's not removing the hand stamp,…that admin ID that we stored in the session.…It's just unsetting $_SESSION['username'],…which was just a convenience that we had earlier.…
So what I'm going to do is I'm going to switch…to auth_functions.php and right here…below log_in_admin, I'm going to add…a new function called log_out_admin.…It is also included in the exercise files…if you want to get it from there.…And it's going to do the exact opposite…of logging in the user.…It's going to unset all of those session IDs,…one for admin ID, last login, and username,…so it handles all the business of logging a user out.…I also have another optional choice here.…
