Logging Out???

[dubt2nv]

I am currently making a website using php for a project at tafe....and am wondering what php code i should use to allow the user to log out properly without the ability for people to return to the log-in pages by pressing back.....basically i have a log-in form that only allows users to log-in if the user has their details entered into the database....and i am jus wondering how i would make the log-out button actually log-out... ???

you using sessions or cookies? or are you just passing the user name/id over every page?

Hope you create a session as soon as the user logs in and you are checking in all the pages if that session exists(if not redirect to login page) . When logging out you can clear all sessions (session_unset();) and redirect to some other page with some message.

If you use cookies , you have to do the same but reset the cookie

if you're using cookies
whatever cookie is keeping the user logged in, set it empty:

[code]
setcookie("cookie_logged_in", "", time()+36000);
[/code]

if you're using sessions, which I hope you are, look up [url=http://www.php.net/session_destroy]session_destroy()[/url] and [url=http://www.php.net/session_unset]session_unset()[/url]
