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：

1. <?php
2. /*
3. *
4. * 陈海波 新二级页面 农历转换成公历
5. *
6. * */
7. // 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
8. class Lunar

10. private $_SMDay = array(1 => 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);//定义公历月分天数
11. private $_LStart = 1950 ;//农历从1950年开始
12. private $_LMDay = array(
13. //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
