heres a issue i have. When a user logs in on the website, it sets a value to indicate they are offline. If they logout through the website, the value is set to indicate the user is offline.
But if the user just closes the website without pressing logout, it still indicates they are online.
How can i make it so it makes them offline once they have closed the website.
my website is using php, html, css and mysql.
The most common approach is to save a timestamp with the user’s last activity instead of just an “online” flag. Update the timestamp on every activity and calculate offline users by checking for users which have been inactive for more than, say, five minutes.
For performance reasons you may want to save the timestamp into the users current session as well and only update your activity timestamp in the database when it is about to expire.
