I have my website that need login for view further information. My problem is that when user login the session is started to a limited time that already define in php.ini file. I want to unlimited this session time when user log in. I already user ini_set() function i-e: 

ini_set("session.gc_maxlifetime",720000); 
ini_set('session.gc_probability',1); 
ini_set('session.gc_divisor',1);

which temproraily set php_ini value of session time. but it coul'nt work.

Is there something im doing wrong?

You can store in a cookie? setcookie(name,value,expire,path,domain,secure) Might be a better way - jagmitg
"unlimited" is not possible, but 60 * 60 * 24 * 365 (31536000) will last you a year. Isn't that enough? 720000 seconds is only 8.3 days (720000 / 60 / 60 / 24). - h2ooooooo

I think you're abusing the session logic. Sessions are all about expiring sometime. Though, you can set a session to 1 year which seems, to me, an "unlimited" one. - user1299518

Set session.gc_probability to 0 before starting the session. This will give the garbage collector a 0% chance of removing session data. You have to do this in all applications that share the same session storage location.

You can try doing it this way:

<?php

 ini_set('session.gc_maxlifetime', 30*60);
 session_start();

 ?>

Second parameter is number of seconds after which data will be seen as 'garbage' and potentially cleaned up.

Ofcourse you can adjust numbers that suit your needs.
