Active Users

[psycorpse]

I have been searching everywhere and I know I have seen it before. But anyway I am looking for a counter that show the current users on the site. If you can post a link that would be great. I am more interested in learning how to make one instead of using it.

You can use a database or file to store the user's IP and last access time. And then check the last access time. If the last access time is less than 15 minutes (or some other number) away from now, then consider the user being 'active'. If the last access time is older than 15 minutes, then erase that entry because the user is considered 'inactive'.

Managing your own sessions or to get detailed data you would use a method such as that described by diego25.

If you are using PHP sessions, the fastest way to get a simple count of users online is to simply count the sessions:
