Question

I need auto-logoff system in my application.

if user not using the application more than thirty minutes.they should log in again.

this is what i need.
lastAccessTime should be lesser than 30 minutes. if lastAccessTime exceeds than 30 minutes user should login again with their credentials.

(currently i auto log off using Lastaccesstime field in My user table (database) and compare lastaccesstime with current time for every page loads, I do not think this is right way.)

is their any way to achieve?
Thanks in advance.

You should specify the SESSION LIFETIME and just use the $_SESSION to see if a user is logged in:

ini_set('session.cookie_lifetime',(60*30)); // 60 seconds times 30 = 30 minutes
