I see what you mean now.
Off the top of my head I think a better approach would be this:
- user logs in, his name and a timestamp are added to the list of active users
- every time a user accesses a page on your list his timestamp is updated to the current timestamp.
- when a user logs out you remove him from the file
- for the chat program, when looking for who is logged in you pick form the list all the people who's timestamp is less than, let's say, 10 minutes old and delete the rest.
The best way to do this of course would be to use a database instead of a text file though :)
