Urgent !! Session_on_end ??

[Anon]

Hi all,

Is there any Procedure to know when a user closes his/her Browser window ???

Like in ASP we can track a user by running a function called session_on_end() .. is there any function avaialable in PHP..

What I want to do is..

I have to track how many users are online rightnow ..

Any help would be appreciated..

your session will never know when someone leaves b/c no headers are sent back after your last page loads unless the client requests another page. the best thing to do is to track when the last time the session was used by the user.

eg. if the user hasn't made a page request in 10-15 minutes from the last updated time, then you can assume that he/she is off-line.

ASP's session_on_end is based on the same principle.

A more important Q is: who actually cares about how many people are online at any time?
You can get that info from your webserver's log, any web-analyzer script can do that.
