In this article we've seen how to implement a users online counter with PHP and MySQL. As mentioned earlier, PHP has no way of tracking a session, so we've had to make do with the tools and information that we do have available.
The way we've tallied and displayed the number of users is the most common way to do so, and will represent the number of users on your site fairly accurately. If you run a web site and would like to show your users how many other visitors are online at the same time as them, then user the support file link below to get the code for this article and modify it to suit your needs!
