Hi All

I am after some code/script that I can use on my pages to display the number of visitors currently on.

Any help please

Thanks

I think you'd have to use cookies and a database, I could be wrong, but I'm pretty sure its server side

I use a database, sessions, and cookies to manage this. Here is the very basic concept...

Remove all sessions older than a 'time to live' (I've set this to 60 minutes for some projects, and 10 minutes on others).
Check for the existance of a session. If one exists, the ID will be passed via cookie or GET/POST method.
If one exists, update the last_activity field (timestamp).
If one does not exist, create a unique id (timestamp with MD5 is nice for this) and insert this into the DB.
