<p>Solution for this </p>

<blockquote>
  <p>if (isset($_SESSION['LAST_ACTIVITY'])
  &amp;&amp; (time() -
  $_SESSION['LAST_ACTIVITY'] > 1800)) {
      // last request was more than 30 minates ago
      session_destroy();   // destroy session data in storage
      session_unset();     // unset $_SESSION variable for the runtime }
  $_SESSION['LAST_ACTIVITY'] = time();
  // update last activity time stamp</p>
