php实现阳历阴历互转的方法

最近对阳历转阴历从而得到相应节日的算法这方面比较感兴趣，于是就在网上搜了一圈。不错，还算是找到一个比较不错的php类，实现了将阳历转换为阴历（农历），阴历转换为阳历的算法，同时还能获取干支纪年，生肖，以及相应的阴历的中文叫法等等，功能还是挺齐全的，在这里分享给大家。
具体类代码如下：

    class Lunar{ 
      var $MIN_YEAR=1891; 
      var $MAX_YEAR=2100; 
      var $lunarInfo=array( 
        array(0,2,9,21936),array(6,1,30,9656),array(0,2,17,9584),array(0,2,6,21168),array(5,1,26,43344),array(0,2,13,59728),

          }else if($num>20&&$num<30){ 
            $res="廿".$dateHash[$num-20]; 
          }else if($num==30){ 
            $res="三十"; 
          } 
        } 
        return $res; 
      } 
    } 

使用方法如下：

    <?php 
    header("Content-Type:text/html;charset=utf-8"); 
    $lunar=new Lunar();
    $month=$lunar->convertSolarToLunar(2013,07,08);//将阳历转换为阴历 
    echo '<pre>'; 
    print_r($month); 

打印结果如下：
Array
(
[0] => 2013
[1] => 五月
[2] => 三十
[3] => 癸巳
[4] => 5
[5] => 30
[6] => 蛇
[7] => 0
)
