本文实例讲述了PHP实现阳历到农历转换的类。分享给大家供大家参考。具体如下：

复制代码 代码如下:<"null","甲","乙","丙","丁","戊","己","庚","辛","壬","癸");    //农历地支
    var $mtwelve=array("null","子(鼠)","丑(牛)","寅(虎)","卯(兔)","辰(龙)",
                   "巳(蛇)","午(马)","未(羊)","申(猴)","酉(鸡)","戌(狗)","亥(猪)");    //农历月份
    var $mmonth=array("闰","正","二","三","四","五","六",
                  "七","八","九","十","十一","十二","月");
    var $mday=array("null","初一","初二","初三","初四","初五","初六","初七","初八","初九","初十",
                "十一","十二","十三","十四","十五","十六","十七","十八","十九","二十",
                "廿一","廿二","廿三","廿四","廿五","廿六","廿七","廿八","廿九","三十");//农历日
//赋给初值
//天干地支
    var $ten=0;
    var $twelve=0;
    function MyPub($cYear,$cMonth,$cDay)
    {
        $total=11;//阳历总天数 至1900年12月21日  
        $mtotal=0;//阴历总天数
        for ($y=1901;$y<$cYear;$y++)
        {
            $total+=365;
            if ($y%4==0) $total ++;
        }
        //再加当年的几个月
        switch ($cMonth){
                 case 12:
                      $total+=30;
                 case 11:
                      $total+=31;

            if ($cYear%4==0 and $cMonth>2)
            {

            $total+=$cDay-1;

            for($j=0;$j<=120;$j++)
