   **$_SESSION['uid']**

value of this variable is getting unset after time cross 2 hours or some more than that, why is it so, even i am not unssetting any variable, is there any server problem or any browser problem

Make changes in your ini file and restart your server, also use `exit` after header — Mr. Alien, Dec 14 '12 at 13:22
If your php.ini is on live server with many projects using the same ini file or you dont have access to it. Try my answer. — Ravi, Dec 14 '12 at 13:31

doing `php -i | grep php.ini` on the server will show you hopefully – Sjors Branderhorst Dec 14 '12 at 13:33

Instead of changing this in php.ini, try this to change the timeout during runtime.

ini_set('session.gc_maxlifetime', 5*60*60); // 5 hours

EDIT

NOTE: Use this code before session_start()

If you do not have access to php.ini and/or do not want to restart your server you may try the following. Look at the session.gc_maxlifetime setting with http://php.net/ini_get like so:

    ini_get('session.gc_maxlifetime')

and you may set it with http://php.net/ini_set like so

    ini_set('session.gc_maxlifetime', 3600*24);

Beware of memory issues and long running scripts though. Also like another answer says: execute before session_start().
