I am trying to subtracting two variables in PHP (time format, "H:i:s"), i.ex: 

$entryscan = '07:15:00';
$exitscan = '16:35:00';

How do I get the work duration? I mean $workduration = $exitscan - $entryscan; so, the answer is $workduration = '09:20:00';

Use php timediff function.

$datetime1 = new DateTime($entryscan);
$datetime2 = new DateTime($exitscan);
$interval = $datetime1->diff($datetime2);
echo $interval->format('%H hours');

%H will give you the difference in hours.

%I will give you the difference in minutes.

%S will give you the difference in seconds.

Try to use php DateTime Class if your php version >= 5.2

$entryscan = '07:15:00';
$exitscan = '16:35:00';

$entryTime = new DateTime($entryscan);
$exitTime = new DateTime($exitscan);
$interval = $entryTime->diff($exitTime);
$workduration = $interval->format('%H:%I:%S');

$entryscan = '07:15:00';
$exitscan = '16:35:00';
$time1 = new DateTime($entryscan);
$time2 = new DateTime($exitscan);
$diffis = $time1->diff($time2);
echo $workduration = $diffis->format('%H:%I:%S');

@Arshid i just edit your code is working fine.
