PHP获取两个日期之间所有月份

function getMonthForDates($sDate, $eDate)
    {
        $sTime = strtotime(date('Y-m-01', strtotime($sDate)));
        $eTime = strtotime(date('Y-m-01', strtotime($eDate)));
        $months = [];
        while ($sTime <= $eTime) {
            $months[] = date('Y-m', $sTime);
            $sTime = strtotime('next month', $sTime);
        }
        return $months;
    }
