Re: who's logged on / how to I find out about other sessions

Hi Christian, What most sites do is to keep track of the latest time that a user requested a page (ie when a page is requested store the current time). Then a definitiion of "logged-in" is made.... usually this is "has requested a page in the last 30 minutes" so the query to count the users whose time of last access was within 30 mins of now. Hope this makes sense, Tom > Hi, > > I'm writing a bbs/messageboard system and am trying to figure out how to tell > what other users are logged on. > > I know I could store the info in a table in my login code but then how do I > find out if people are logged out > with out making them actually use a logout button or the like. > > I was going to do it that way but I have noticed that phpnuke sites can list > the number of logged in sites etc; > but their code is a little beyond me atm > > Is there a way to list other session vars ? > > any ideas welcome > > with thanks > > Christian > > > Christian Cable > ICT Assistant > Careers Service; Lancaster University > Tel: (01524) 594072 Fax: (01524) 592072 > http://www.lancs.ac.uk/staff/cable/ > > > > -- > PHP Database Mailing List (http://www.php.net/) > To unsubscribe, e-mail: php-db-unsubscribe@lists.php.net > For additional commands, e-mail: php-db-help@lists.php.net > To contact the list administrators, e-mail: php-list-admin@lists.php.net >
