Question

Is there any PHP function that does the same thing as SQL function TIMEDIFF() ?

Here is my code:

$to_time = array_search( 'time2.Time', $aCols );
$from_time = array_search( 'time1.Time', $aCols );
$value= ;  

I need to get values in this format HH:MM:SS

I use this version : PHP 5.2.17

If you use php 5.3 or after you can use the following code

$to_time = new DateTime(array_search( 'time2.Time', $aCols ));
$from_time = new DateTime(array_search( 'time1.Time', $aCols ));
$interval = $date1->diff($date2);
$value = $interval->format('%H:%i:%s');

or before 5.3 try something like this:

$date1 = strtotime("2012-09-13 12:14:24.453");
$date2 = strtotime("2012-09-15 14:21:28.453");
$interval = $date2 - $date1;
$seconds = $interval % 60;
$minutes = floor(($interval % 3600) / 60);
$hours = floor($interval / 3600);
echo $hours.":".$minutes.":".$seconds;
