Setting timeouts for sessions

[MortimerJazz]

Can someone explain to me how you do this?

Basically, I want to ensure that if someone logs in and then leaves the computer for say 20 minutes, the session automatically ends and a user is forced to log in again.

Thanks alot,

It is set in your php.ini, the directive is called "session.gc_maxlifetime". Set it to the number of seconds you want it to be in your php.ini file, or use [url=http://www.php.net/ini-set]ini_set("session.gc_maxlifetime", $number_of_secs)[/url] to do so.

Orio.

So it's something that I need to get my host to change then?

No, you can change it yourself. Orio has provided the code for your which is this:
[code]ini_set("session.gc_maxlifetime", number_of_secs)[/code]

That will be needed to be added to every page that uses sessions.

Or if your account allows the use of .htaccess files then you can the following into a .htaccess file:
[code]php_value session.gc_maxlifetime "number of secs"[/code]
