Can I at least read the session files for all sessions?

[Bob Stearns]

Right now, I am attempting to see how many users are "signed on" to my
system. Since this is, at best, rather tenuous in a WEB environment, I
thought to read the active session variables and see how many sessions
there were.

I'd propose to write timestamp to DB each time the registered user visit
the site's pages. Then you define the default timeout and make querry -
something like that :
SELECT COUNT(username) FROM table_name WHERE last_logged >current_time -
timeout
think this is more simple.

That won't really work since the presence of a session file doesn't
mean the session is active. Files for session that have expired stay in
the folder under garbage collection occurs. By default, PHP garbage
collects about once every 100 requests. When traffic is low (say, in
the middle of the night), dead sessions could remain for a long time.

As was suggested, it's probably easier to save the info in the database.

Thanks, I'll work on that.
