datetime - Calculate difference between 2 times in hours in PHP

Question

I have two times - For eg- the current time - 08:24 and date is 02/01/2013 in dd/mm/yyyy format and I have another time at 13:46 and date is 31/12/2012 . So, how can I calculate the difference between the 2 times in hours using PHP. (i.e. 42.63 hours) Thanks in advance.

Answer 1

Convert them both to timestamp values, and then subtract to get the difference in seconds.

$ts1 = strtotime(str_replace('/', '-', '02/01/2013 08:24'));
$ts2 = strtotime(str_replace('/', '-', '31/12/2012 13:46'));
$diff = abs($ts1 - $ts2) / 3600;
