what exactly do you mean by that last sentence? I don't quite follow it.

I mean if I knew all active session id's I could compare them to the
members_online table.
An example in pseudo code:
// Member logs in, store session id, login datetime, last visit datetime:
INSERT INTO members_online
// Get active session ids from table:
php code
// Compare active session ids with table sessions:
for ($i=0; $i < table rows; $i++){
if ( !isset( session id from member $i )) {
DELETE member from table
}
}

I already use a class to perform this task. The problem is if a member
closes the browser windows and then tries to login again before the
specified timeout.
Does Apache have a function like asp Session_OnStart, Session_OnEnd ?
I am using IIS and PHP 5.0.4
Thanks in advance.
Pedro.
