PHP生成一段时间之间的月份列表

今天项目中需要生成一段时间的月份列表，自己随便写了个，以后再继续优化了。使用时可根据自己需要进行修改。

function getMonthList ($timestamp1, $timestamp2)

{

    $yearsyn = date('Y', $timestamp1);

    $monthsyn = date('m', $timestamp1);

    $daysyn = date('d', $timestamp1);

    

    $yearnow = date('Y', $timestamp2);

    $monthnow = date('m', $timestamp2);

    $daynow = date('d', $timestamp2);

    

    if ($yearsyn == $yearnow)

    {

        $monthinterval = $monthnow - $monthsyn;

    }

    else if ($yearsyn < $yearnow)

    {

        $yearinterval = $yearnow - $yearsyn -1;

        $monthinterval = (12 - $monthsyn + $monthnow) + 12 * $yearinterval;

    }    

    

    $timedata = array();

    for ($i = 0; $i <= $monthinterval; $i++)

    {

        $tmptime = mktime(0, 0, 0, $monthsyn + $i, 1, $yearsyn);

        $timedata[$i]['year'] = date('Y', $tmptime);

        $timedata[$i]['month'] = date('m', $tmptime);

        $timedata[$i]['beginday'] = '01';

        $timedata[$i]['endday'] = date('t', $tmptime);

    }

    

    $timedata[0]['beginday'] = $daysyn;

    $timedata[$monthinterval]['endday'] = $daynow;

    

    unset($tmptime);

    

    return $timedata;

}
