The 'diff' method applies to a DateTime Object..

$from_time = '2015-09-25 11:52:22';
$to_time   = '2015-09-25 01:06:57';

  $date_a = new DateTime($from_time);
  $date_b = new DateTime($to_time);
//$interval =     date_diff($date_a,$date_b);
  $interval = $date_a->diff($date_b);
  echo $interval->format('%h:%i:%s');

// 10:45:25
