How to make a SESSION to expire?

How to make a session to comit suicide after certain time?(autoexpire).

This is the deal, I have a intranet that requieres that the users, to be active, other wise they sould be kicked out (of the sistem not from the company 😃 ).

We want to avoid that IF some one let his Intranet Session open for more that 3 minuts the session must expire.

So far I use cookies and Java Script to do this, and I CLEAR ALL THEM when this happen, but thats with JavaScript, and the $_SESSION vars are still INTACT

So, is some PHP routine that sets an "autoexpire" or "expiration time", parameter that we can set when we create the session?

Set a meta tag to redirect to a page which will expire them after your certain amount of time.

A better way is to simply use the function session_cache_expire(). You will find more info about it at: http://www.php.net/manual/en/function.session-cache-expire.php
