Answer 1

Another way is to use PHP's date-related classes. The example below uses DateTime::diff() to get a DateInterval object ($interval). It then uses the interval's properties to arrive at the total number of hours in the interval.

$a = DateTime::createFromFormat('H:i d/m/Y', '08:24 02/01/2013');
$b = DateTime::createFromFormat('H:i d/m/Y', '13:46 31/12/2012');

$interval = $a->diff($b);
$hours    = ($interval->days * 24) + $interval->h
          + ($interval->i / 60) + ($interval->s / 3600);

var_dump($hours); // float(42.633333333333)
