Question

Here’s my function

<?php    
//Find time difference
    function timeDifference($timeEnd, $timeStart){
      $tResult = strtotime($timeEnd) - strtotime($timeStart);
      return date("G:i", $tResult-3600);
    }
?>

And an example

<?php
   echo timeDifference(12:00:00,08:30:00);
?>

The results on my localhost was fine but online on my server it’s showing 21:30 when it’s supposed to be 3:30. What could do that?

UPDATE

Here my solution for php 5.2

<?php
//Find time difference
function timeDifference($timeEnd, $timeStart){
  $tResult = round(abs(strtotime($timeEnd) - strtotime($timeStart)));
  return gmdate("G:i", $tResult);
}
?>

Thanks for the help guys

If you’re using PHP 5.3, it comes with a built-in date_diff() function.

It might be easier than trying to debug your own function.

By the way, the code you’ve given:

echo timeDifference(12:00:00,08:30:00);

is never going to work, because you haven’t got quotes aruond the time strings. I assume that’s a typo in the question, since you claim that the function is returning results (even if they’re incorrect)
