PHP: Loop through all months in a date range?

Question

If I have a start date (say 2009-02-01) and an end date (say 2010-01-01), how can I create a loop to go through all the dates (months) in the range

Answer 1

I have a method which is optimal in results :

$begin = new DateTime( '2014-07-14' );
$end = new DateTime( '2014-08-01' );
$end = $end->modify( '+1 month' );
$interval = DateInterval::createFromDateString('1 month');

$period = new DatePeriod($begin, $interval, $end);

foreach($period as $dt) {
    var_dump($dt->format( "m" ));
}

A plus for the method of @Glavic
