But i need like following : 24hrs 3 minutes 5 seconds

If you're using PHP 5.3 or better (which you should be), you can use the built in DateTime class to produce a DateInterval which can be formatted easily.

$time_one = new DateTime('2010-07-29 12:43:54');
$time_two = new DateTime('2010-07-30 01:23:45');
$difference = $time_one->diff($time_two);
echo $difference->format('%h hours %i minutes %s seconds');

DateTime was introduced in 5.1, but DateInterval is new to 5.3.
