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：
classLunar{
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),

使用方法如下：

$month=$lunar->convertSolarToLunar(2013,07,08);//将阳历转换为阴历
echo'<pre>';
print_r($month);
