run code in 300+ PHP versions simultaneously
<?php $start = new DateTime('2010-12-02'); $start->modify('first day of this month'); $end = new DateTime('2012-05-06'); $end->modify('first day of next month'); $interval = DateInterval::createFromDateString('11 months'); $period = new DatePeriod($start, $interval, $end); foreach ($period as $dt) { echo $dt->format("Y-m") .
