php陽曆轉陰曆(農曆),陰曆轉陽曆的方法

 由於最近一個項目設計到將陽曆轉陰曆從而得到相應節日的演算法，對這方面不是很瞭解，於是就在網上搜了一圈。不錯，還算是找到一個比較不錯的php類，實現了將陽曆轉換為陰曆（農曆），陰曆轉換為陽曆的演算法，同時還能擷取幹支紀年，生肖，以及相應的陰曆的中文叫法等等，功能還是挺齊全的，在這裡共用一下。

具體類代碼如下：

使用方法如下：

<?phpheader("Content-Type:text/html;charset=utf-8");$lunar=new Lunar();//http://www.Alixixi.com/php-function/867.html$month=$lunar->convertSolarToLunar(2013,07,08);//將陽曆轉換為陰曆echo '<pre>';print_r($month);

列印結果如下：

Array
(
    [0] => 2013
    [1] => 五月
    [2] => 三十
    [3] => 癸巳
    [4] => 5
    [5] => 30
    [6] => 蛇
    [7] => 0
)

具體數組中各個元素代表什麼意思，這裡就不用解釋了吧。
