You probably has configured your chat client page to make a timely refresh,
so the user can get new messages every time the page is refreshed.
I don't know if you allow the user to set up the refresh interval, any way
you can have a logged users table with their login time and last refresh
time. If current time is (for security) n times the refresh interval ( say
twice ) you may log them out. Be careful with users connection speed !
You have all the control of your database so you know if the user didn't
refresh the chat page in the last n refresh period. Messy ?
HTH.

Assunto: [PHP-DB] Desperate Help needed
Hi,
I made a database chatroom that seemed to be working perfectly fine - now,
it seems, if more than two people log in, the 1st person of the three
automatically gets logged out - its because i tried to make an automatic log
off for those who cross the window....
How do you detect if a person has closed the window (hence killing the
cookie) without logging off (so the database still has him listed, and
therefore is shown to be online)?
Here's the scenario:
1. one table lists the chatters' names
2. second table has 25 rows for each messages, they keep getting replaced as
the new messages come in
the problem: the chatters table lists those users who logged out ages ago...
thanks.
