PHP DateTime modify to specifc date in month

I am trying to use the php DateTime objects modify function to modify he date to a specific date in the month i.e. 10th or 20th etc.

I have tried all of the following, none of which work:

$d = new DateTime();

$d->modify('10th day');
$d->modify('10th');
$d->modify('10th of this month');
$d->modify('10th of the month');

Try this:

$d = new DateTime('first day of this month');
$d->modify('+9 day');

PS: Nevertheless, I guess a better way to use

$cMonth = date('n');
$cYear = date('Y');
...
$d->setDate($cYear, $cMonth, 10);

Assuming you don't know the year and month (if you do, use DateTime::setDate()), one way to do this would like this:

$day = 10; // 10th of the month
$dt = new DateTime('first day of this month');
$dt->modify('+' . ($day - 1) . ' days');

I have a feeling that there's also a way to do it strictly through the constructor, but like you, I couldn't figure out the magic string. Odd that "first day of the month" works, but "tenth day of the month" does not.

Edit: Apparently it's impossible to do this through the constructor. Even Rasmus suggests doing it this way instead.

You want to use DateTime::setDate

$date = new DateTime();
$date->setDate(2001, 2, 10);
