PHP 5.3
$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('1 month');
$period = new DatePeriod($start, $interval, $end);
foreach ($period as $dt) {
echo $dt->format("Y-m") . "<br>\n";
}
PHP 5.4或更高版本
$start = (new DateTime('2010-12-02'))->modify('first day of this month');
$end = (new DateTime('2012-05-06'))->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$period = new DatePeriod($start, $interval, $end);
foreach ($period as $dt) {
echo $dt->format("Y-m") . "<br>\n";
}
我们将开始日期和结束日期修改为每月第一天的部分很重要。如果我们不这样做,则当前日期要比2月的最后一天高(例如,非-年为28,leap年为29),则跳过2月。

您必须在同一年的两个月与不同年份的两个月之间有所不同。
$year_min = substr($row['contractStart'], 0, 4);
$year_max = substr($row['contractEnd'], 0, 4);
$month_min = substr($row['contractStart'], 5, 2);
$month_min = substr($row['contractEnd'], 5, 2);
$period = array();
try {
if ($year_min > $year_max)
throw new Exception();
else if ($year_min == $year_max)
if ($month_min > $month_max)
throw new Exception();
for ($month = $month_min; $month <= $month_max; $month++) {
$period[] = $month . '-' . $year;
}
else {
for ($month = $month_min; $month <= 12; $month++) {
$period[] = $month . '-' . $year_min;
}
for ($year = $year_min + 1; $year < $year_max; $year++) {
for ($month = $month_min; $month <= $month_max; $month++) {
$period[] = $month . '-' . $year;
}
}
for ($month = 1; $month <= $month_max; $month++) {
$period[] = $month . '-' . $year_max;
}
}
implode("<br />\r\n", $period);
}
catch (Exception $e) {
echo 'Start date occurs after end date.'
}
那是艰难的方式。现在,已经有一种快速简便的方法作为答案,我建议您选择该方法。

function getMonthsInRange($startDate, $endDate) {
$months = array();
while (strtotime($startDate) <= strtotime($endDate)) {
$months[] = array('year' => date('Y', strtotime($startDate)), 'month' => date('m', strtotime($startDate)), );
$startDate = date('d M Y', strtotime($startDate.
'+ 1 month'));
}
return $months;
}
