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

Example of DateTime, DateInterval and DatePeriod class combination :

$start = new DateTime('2009-02-01');
$interval = new DateInterval('P1M');
$end = new DateTime('2011-01-01');
$period = new DatePeriod($start, $interval, $end);

foreach ($period as $dt) {
    echo $dt->format('F Y') . PHP_EOL;
}
