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

I would solve this like that. First, I'd create an instance of your given datetime object. Then, I'd create another datetime object which is 7 days later than the initial one. And finally, I'd format it the way you like.

With meringue library, this is quite intuitive and elegant. Here's the code:

(new Future(
    new FromCustomFormat('F j, Y', 'March 3, 2011'),
    new NDays(7)
))
    ->value();

The result is a string in ISO8601 format. If you like, you can format it anyway you like using the same ISO8601 syntax:

(new ISO8601Formatted(
    new Future(
        new FromCustomFormat('F j, Y', 'March 3, 2011'),
        new NDays(7)
    ),
    'F j, Y'
))
    ->value();

The code above uses meringue library. Here's a quick start, you can take a look if you want.
