Most sites handle online users in their database, store a timestamp each time a user loads a page. When you want to display the online users, check where the timestamp is between now and a few minutes ago. Note that without javascript (or flash/java/etc) there is no way to truly know if the user left or not. The session will stay active for a long time, depending on your php.ini settings. - Matijn
