I have been looking for an answer for a few hours now, but I can’t find one.
I’m writing a simple
script. The user sets their work start and end time. So, for example, somebody is working from 8:00 to 16:00.
How can I subtract this time to see how long the person has been working?
I was experimenting with
strtotime(); but without success…
A bit nicer is the following:
$a = new DateTime('08:00'); $b = new DateTime('16:00'); $interval = $a->diff($b); echo $interval->format("%H");
That will give you the difference in hours.
If you get valid date strings, you can use this:
$workingHours = (strtotime($end) - strtotime($start)) / 3600;
This will give you the hours a person has been working.
Another solution would be to go through the Unix-timestamp integer value difference (in seconds).
<?php $start = strtotime('10-09-2019 12:01:00'); $end = strtotime('12-09-2019 13:16:00'); $hours = intval(($end - $start)/3600); echo $hours.' hours'; //in hours //If you want it in minutes, you can divide the difference by 60 instead $mins = (int)(($end - $start) / 60); echo $mins.' minutues'.'<br>'; ?>
This solution would be a better one if your original dates are stored in Unix-timestamp format.
