ok.... still have questions regarding how to handle a user/session of a user who kills their browser. in this case, the user's session information would still be in the db for the session handler... am i correct in understanding/assuming that i could iterate through the list of sessions in the session handler, and the session information for users who aren't on the site, will essentially be invalid??? also, i'm trying to get my hands around the garbage collection function, as it relates to users who aren't on the system any more... information that i've seen in the articles haven't given me insight for this isssue... if i can see how to deal with this situation, then i can craft a way for an admin to more or less be able to generate a list of users/people who are actually on the system/site. as an exercise, i took a look at mambo (the cms) and realized that it doesn't handle users who simply shut down their browser while on the system... thoughts/comments... -bruce -----Original Message----- From: Philip Hallstrom [mailto:php@xxxxxxxxxxxxxxx] Sent: Tuesday, September 13, 2005 3:43 PM To: bruce Cc: juzamjedi@xxxxxxxxx; php-general@xxxxxxxxxxxxx Subject: RE: trying to figure out the best/efficient way to tell who is logged into a site.. > any code/pointers to this... > > i've been doing the google/search thing and haven't come across anything > which relates to what i'm searching for... > > so.. any help in this area would be greatly appreciated!! > > i would have thought there would be articles/open course code/apps on this!! > > -thanks > > bruce http://www.php.net/manual/en/function.session-set-save-handler.php Also try zend.com in the tips/articles/code-snippets section. > > > -----Original Message----- > From: Jason Barnett [mailto:juzamjedi@xxxxxxxxx] > Sent: Tuesday, September 13, 2005 2:25 PM > Cc: php-general@xxxxxxxxxxxxx > Subject: Re: trying to figure out the best/efficient way to tell > who is logged into a site.. > > > Close: You mix both of these ideas. > > Create a custom session handler.
