Ok i've just set up a control pannel for a client of mine so they can edit add delete news posts and events,

Now the sesions all work fine but they time out after a few minutes, is there any way i can increase the time out of the sessions? I've been looking at the manual

http://us4.php.net/manual/en/ref.session.php

session.cache_expire "180" PHP_INI_ALL

And i think thats the setting i need o chnage but i have no idea how to do it? Could anyone assist me on this?

Thanks
