Session timeout issue in php
<p>I have set session timeout time for 20 Minutes as below.Sometime  the session timeout is happening in two or three minutes.</p>

<pre><code>ini_set('session.gc_maxlifetime',   1200);

ini_set('session.cookie_lifetime',  1200);

ini_set('session.gc_probability',   1);

ini_set('session.gc_divisor',   100);
</code></pre>

<p>What could be the issue?</p>
