datetime - How do I find the hour difference between two dates in PHP?

Question

I have two dates, formated like "Y-m-d H:i:s". I need to compare these two dates and figure out the hour difference.

Answer 1

You can convert them to timestamps and go from there:

$hourdiff = round((strtotime($time1) - strtotime($time2))/3600, 1);

Dividing by 3600 because there are 3600 seconds in one hour and using round() to avoid having a lot of decimal places.
