session_destroy is what you're looking for. http://us2.php.net/function.session-destroy

//Destroy the session.
session_destroy();

Do you mean all the users on the server or is this for users of a certain program?

Session are specific to each user. You might be able to try deleting the server-side cookies from the session cache (if you have sufficient permissions), otherwise, I'de say you need to build a customized session handler of some sort.

session_destroy would do the trick and you can clear all variables using the unset function.

No it won't. That'll just destroy the session for the current user. The OP will have to do something like Thorpe's suggestions if they want to destory sessions for all users.
