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

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

Solution 1:

$date = "Mar 03, 2011";
$date = strtotime($date);
$date = strtotime("+7 day", $date);
echo date('M d, Y', $date);

Solution 2:

The "+1 month" issue with strtotime

As noted in several blogs, strtotime() solves the "+1 month" ("next month") issue on days that do not exist in the subsequent month differently than other implementations like for example MySQL.

$dt = date("Y-m-d");
echo date( "Y-m-d", strtotime( "$dt +1 day" ) ); // PHP:  2009-03-04
echo date( "Y-m-d", strtotime( "2009-01-31 +2 month" ) ); // PHP:  2009-03-31

Solution 3:

echo date('d/m/Y', strtotime('+7 days'));

Solution 4:

Another more recent and object style way to do it :

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

php doc of datetime add

Solution 5:

yes

$oneweekfromnow = strtotime("+1 week", strtotime("<date-from-db>"));

on another note, why do you have your date in the database like that?
