For example, I have got the following code:

$time1 = 14:02:21;
$time2 = 12:04:48;
$time3 = 08:19:17;

$addtime = $time1 + $time2 + $time3;
echo $addtime;

Which would return 34:26:26

I am trying to do this inside of a while loop:

Before while loop: 

$on_duty_time = '';

Inside of While Loop: 

$on_duty_time += strtotime($row2['driving_timer']);

After the While Loop:

$on_duty_time -= strtotime('00:00:00');
$time = date('H:i:s', $on_duty_time);
echo $time;

This code worked when I had two timestamps only, which were 00:35:40 and 00:00:21 (being called in by the variable $row2['driving_timer']), which gave me the end result of 00:36:01.

But now one of my loops has the timestamp: 00:01:36, but it is returning 17:01:36 when I try to put it through my while loop code.

Any ideas on why this is happening?

Or perhaps, does anyone know of a better way to add these timestamps together whilst using a while loop?

  • You lost me at `Which would return 34:26:26`... Say what? – Mike Jun 02 '16 at 22:19
  • Also `$time1 = 14:02:21;` is a syntax error. – Mike Jun 02 '16 at 22:20
  • Think of the times as time on a stop watch, where 17:34:02 is 17 hours, 34 minutes, and 2 seconds. – Kelsey Jun 02 '16 at 22:21
  • 18 + 12 + 14 != 34 – Mike Jun 02 '16 at 22:24

  • @Mike My bad, meant to make it 08 not 18. – Kelsey Jun 02 '16 at 22:27
