php - add + 7 days to date format mm dd, YYYY

Question

I have date of this format March 3, 2011 in database and I need to extend it with 7 days. I mean

 $date = $date + 7

. Is there any build in function to do that ?

Answer 1

Another more recent and object style way to do it :

$date = new DateTime('now');
$date->add(new DateInterval('P7D'));
