This can't be that hard but after hours of reading and testing I've got very comfused and a little angry with my PC, I know it's not its fault really....

What I need is a way to insert the duration time from two input text boxes named/ID'ed TripStart and TripEnd, when the form is posted all I need is a calculation of time passed from TripStart and TripEnd.

i.e. user enters 10:30 and 12:30, I need both those added to database (can do this ok), but also in another field called Duration the results of the calculation, 2:00. should the time be entered 23:30 and 03:30 the value added should be 4:00.

Any help would be good, pretty good at the database side of things, its the PHP that is killing me, lol...

High points as need a fast and clear to follow method, willing to increase points if needed.

Please find below example:
<?
function calc($start, $end){
	$a = split(":", $start);
	$b = split(":", $end);
	
	$start_min = $a[0] * 60 + $a[1];
	$end_min = $b[0] * 60 + $b[1];
	
	if ($end_min < $start_min)	$end_min += (24 * 60); 
	
	$diff_min = $end_min - $start_min;
	return intval($diff_min / 60).":". substr("0".($diff_min % 60), -2);
}
 
$TripStart = "23:30";
$TripEnd = "03:30";
 
echo calc($TripStart, $TripEnd);
?>
