Calculating Time difference between two times in hh:mm format - PHP

Question

I am trying to calculate the time difference in hours between to times in format hh:mm. The problem is the data is in both 12 hour and 24 hour. eg. 23:55 - 00:10 , 12:10 - 01:02, 10:50 - 11:10 etc..

I tried the method given here PHP - hours difference (HH:MM format)

I need a function with all conditions to handle the 24h, 12h to calculate the time difference in hours.

Many thanks.

Create \DateTime objects for the times you want to compare and use http://php.net/manual/en/datetime.diff.php to compare them — GordonM, Sep 18 '17 at 08:37

The code in linked solution is fine except over midnight case. If you assume positive difference (start before end) - you may add 1 day (in seconds) when it appears to be negative. Just change return statement to:

return ($timeDiff > 0) ? $timeDiff : $timeDiff + 24*60*60;
