session.gc_maxlifetime ntoworking for me

Question

i want to set session time out limit by 3 min ,

i have used this in the page

ini_set("session.gc_maxlifetime", "50"); not working

Answer 1

The unit for the session.gc_maxlifetime value is seconds. So you would need to set it to 180 seconds to express 3 minutes.

But besides that, session.gc_maxlifetime is not reliable (see this post for an explanation). You should better implement that on your own to have your session expired after exactly 3 minutes.

Answer 2

The session will live as long as the file is left on the harddrive. They are cleaned out by a garbage collector. The garbage collector is run approximately every hundred page loads on the server (this is rather random, the "every hundred" page loads is just an average).

Also, the age of the session is inactive age, not total age. The timer will be reset for that session every time the user does a request.
