users online

[Anon]

I have a problem, i want to make a script that checks current users online on my site.

I have come as far as log user i mysql database when they arrive to my site, and i can count users who have been logged.

The problem is, how do i delete inactive users, users who have left on such a dynamic way as possible ?

If users X, Y and Z are logged in on my site then user count is 3, but user Y leaves the site to visit another one, then i want to 3-1 dynamicly in database.

This is the way i had in mind, do you have a better, faster way, please tell me.

sigh:

get some random code and timestamp. store it as cookie to user and your server db. then simply check this cookie and store new timestamp everytime user has visited some page - set your idle for eg. 1 minute... when timestamp in db expires, user (probably) has logged out...
