Expression for DateTime::modify() to change day of month

I have a DateTime object and I need to move it to the next day X of month. E.g., if X is 15:

2011-02-03 ⇒ 2011-02-15 # Earlier than 15, stay on this month

2011-02-15 ⇒ 2011-02-15 # Today's 15, stay on today

2011-02-20 ⇒ 2011-03-15 # Later than 15, move to next month

I know I can use a combination of DateTime::format() and DateTime::setDate(), but is it possible to make it with a single call to DateTime::modify()?

! It must also work under PHP/5.2.14.

Expressions that contain "day 15" do not even parse.

$x = 15; // day 15 of the month
$d = $date->format('d');
$m = $date->format('m');
$y = $date->format('Y');

$date->setDate($y , $m , $x); // set the wanted day for the month

//if the wanted day was before the current day, add one month
if( $d > $x ){ // is next month's one.
   $date->modify($date, '+1 month');
}
