Adding months to a existing date?

Question

I have a date where I need to add months to, but somehow it returns the epoch date

$duration = 28;
$row[\'end_date\'] = \'2010-09-22 0000:00:00\';

$newEndDate =         


        

Answer 1

$newEndDate = strtotime(date("Y-m-d", strtotime($date)) . " +1 month");
