How to increase your session time out PHP

/*********************** Increase the session time out *****************/
$values = $_SESSION;

// keep session config
$trans = ini_get( 'session.use_trans_sid' );
if( $trans ) {
ini_set( 'session.use_trans_sid', 0 );
}
$cookie = session_get_cookie_params();

// create new session id
$id = 0;
while (strlen($id) < 32) {
$id .= mt_rand(0, mt_getrandmax());
}

$id = md5( uniqid($id, true));

// kill session
session_destroy();

$cookie['lifetime'] = 7*60; // minutes * 60

// restore config
ini_set( 'session.use_trans_sid', $trans );
session_set_cookie_params( $cookie['lifetime'], $cookie['path'], $cookie['domain'], $cookie['secure'] );

session_cache_expire($cookie['lifetime'] / 60);
ini_set('session.gc_maxlifetime', $cookie['lifetime']);
// restart session with new id
session_id( $id );
session_start();
$_SESSION = $values;
