Whose Online? PHP Script

[JAB Creations]

I'd like to find and use a PHP script that like Vbulletin can display a list of those who are online within a set limit of time. I see the opposing language by MS plastered all over the net (dont post the a word as I trued -a.p in my search so others smart like myself in their search may find this page in the future).

Anyway does anyone have or know of such a php script? The reason I can't continue using it is because the chgdir is messing with my another script. I do not know how to reset chgdir once set and no one has posted that. If they did I'd not have to post this alternatively. :-\

( May be ) idea: use a 'cookie_table' or 'session_table' with a two timestamp data-type; keep one timestamp constant during login, update next timestamp after few minutes ( say 15 min or 5 min ), if user is still logged in.

Vbulletin is a best forum ( but is not free ); PHPbb2 next best and free option, you may try.
