I am trying to figure out to calculate how much I earn throughout a day at work. I have a script now, that calculate how many hours I work a day. But the problem is that my salary is different throughout the day. The point is that I have a starttime and endtime. These hours is saved in hours_worked. So lets say I am working from 03.00 PM to 11.00 PM. Then I need to run through those hours I have choosen, and then give me the salary a day. Fx:
03.00 PM - 11.00 PM:
08.00 - 06.00 PM - 100 kr pr hour -> 300 kr (Morning)
06.00 - 10.00 PM - 150 kr pr hour -> 600 kr (Evening)
10.00 - 11.00 PM - 200 kr pr hour -> 200 kr (Late Evening)
The final result should be 1100 kr.
I have tried to make a while loop, but that didn't do it for me. I tried to make 3 variables, to save the numbers in throughout the loop, and then get them calculated at the end. But I am really in doubt if I have to use while loop, foreach, for loop etc. I would guess I have to get som "if/else" in the code aswell? But can somebody give me a hint what to do?
Best Regards Mads

$early_time;
$middle_time;
$late_time;
$hours_worked = $end_time - $start_time;
echo "Total hours worked : " . $hours_worked."<br>";
