Hi.

This is a common problem, without a very good solution.
The problem here is that there is no reliable way of tracking whether the user has actually closed the browser or not.

The best solution I have seen is a timeout based logout system.
That is, whenever the client opens a page, log the time into a database.
If the client remains inactive, not requesting new pages, for a given amount of time, he will be considered offline.

You could even expand this to include AJAX, which would periodically update the database time-stamp while the page is open, thus keeping the user online if for some reason he spends more time than the timeout period on a single page.

Hi, waqasahmed996

Another way of doing it is to change the session save handler to a custom class, so you can store your sessions in your database (making the destoy function to delete the record) and also save the session_id in your user's table, make a file that'll be always included that checks that db to see if the session for the given user still exists in the table if it doesn't then you can consider the user offline. If your site recieves lot's of visits, then you may want to put that script in a cron, so it doesn't get executed thousands of times, reducing the load to your db.
