How to calculate the time difference between two timestamps using PHP?

edit

You can use the strtotime() function to convert the timestamps into Unix timestamps and then subtract them to get the time difference in seconds. Here's an example:

$timestamp1 = '2020-12-01 08:30:00';
$timestamp2 = '2020-12-01 09:15:30';

$time1 = strtotime($timestamp1);
$time2 = strtotime($timestamp2);
$timeDiff = $time2 - $time1;

echo "Time difference: " . $timeDiff . " seconds";

This will output:

Time difference: 2730 seconds

To convert the time difference into minutes, hours, or days, you can divide it by the appropriate factor:

$minutesDiff = $timeDiff / 60;
$hoursDiff = $timeDiff / (60 * 60);
$daysDiff = $timeDiff / (60 * 60 * 24);

Keep in mind that these calculations are based on the Unix timestamp, which is the number of seconds since January 1, 1970. If your timestamps are in a different format or time zone, you may need to adjust the calculations accordingly.
