<?php $oneMonth = new \DateInterval('P1M'); $startDate = \DateTime::createFromFormat('d H:i:s', '1 00:00:00')->sub(new \DateInterval('P24M')); $period = new \DatePeriod($startDate, $oneMonth, 24); foreach($period as $date){ //$date is an instance of \DateTime. I'm just var_dumping it for illustration var_dump($date); }
