PHP 实现公历日期与农历日期的互转换

　　PHP 实现公历日期与农历日期的互转换

　　前言：

　　今天根据客户的需求对时间进行了转换，就是客户要求增加农历日期的显示，在网上抄袭了一段，稍微修改了一下运行成功了，不难的，改动的很少的.

　　示例代码：

　　 <?php /* * * 陈海波 新二级页面 农历转换成公历 * * */ // lunar.php 新建这个php文件，所有的代码无需改，需要改的是下面teacher.php 的几行 class Lunar { private $_SMDay = array(1 => 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);//定义公历月分天数 private $_LStart = 1950 ;//农历从1950年开始 private $_LMDay = array( //差：该年的农历正月初一到该年公历1月1日的天数；1~12：农历月份天数；闰：如有闰月，记录该月平月天数 // 差 1 2 3 4 5 6 7 8 9 10 11 12 闰 array(47,29,30,30,29,30,30,29,29,30,29,30,29),
