How to plus or minus hours in laravel?-CodePudding

I have the following case but don't know how to do it, can anyone help me.

Clock Clock In: 8:00, Clock Out: 17:00 => Total: 9:00

1st break Start Break: 11:00, End Break: 13:00 => Total break1: 2:00

Second break Start Break: 15:00, End Break: 15:30 => Total break2: 0:30

$startTime = Carbon::parse('8:00'); 
$endTime = Carbon::parse('17:00');
$duration = $endTime->diffInMinutes($startTime);
$totalminutes  = $duration;
dd(date('H:i', mktime(0, $totalminutes)));
Total : 9:00

I want to plus the hours of break1 and break2

2:00 0:30 = 2:30

and total clock minus total break

9:00 - 2:30 = 6:30

everyone helps me, thanks everyone

CodePudding user response：

You can calculate the duration the same way for breaks except that you need to subtract them from the total minutes instead of adding them.

$startTime = Carbon::parse('8:00');
$endTime = Carbon::parse('17:00');

$firstBreakStart = Carbon::parse('11:00');
$firstBreakEnd = Carbon::parse('13:00');

$secondBreakStart = Carbon::parse('15:00');
$secondBreakEnd = Carbon::parse('15:30');

$totalMinutes = $startTime->diffInMinutes($endTime);
$totalMinutes -= $firstBreakStart->diffInMinutes($firstBreakEnd);
$totalMinutes -= $secondBreakStart->diffInMinutes($secondBreakEnd);

dd(date('H:i', mktime(0, $totalMinutes)));
