Answer 1

The easiest way without reinventing the wheel. This'll give you the full months difference. I.e. the below two dates are almost 76 months apart, but the result is 75 months.

date_default_timezone_set('Asia/Tokyo');  // you are required to set a timezone

$date1 = new DateTime('2009-08-12');
$date2 = new DateTime('2003-04-14');

$diff = $date1->diff($date2);

echo (($diff->format('%y') * 12) + $diff->format('%m')) . " full months difference";
