Add six months in php

I’m trying to get the month, six months out from the current date.

I’ve tried using:

date('d', strtotime('+6 month', time()));

But it doesn’t seem to work, always returns 01. Is there a better way to do this?

Thank you!

Answer

I find working with DateTime much easier to use:

$datetime = new DateTime();
$datetime->modify('+6 months');
echo $datetime->format('d');

or

$datetime = new DateTime();
$datetime->add(new DateInterval('P6M'));
echo $datetime->format('d');

or in PHP version 5.4+

echo (new DateTime())->add(new DateInterval('P6M'))->format('d');
