Copy code The code is as follows:

/**
* 公农历转换(1912 - 2012)
*
* Usage:
* // 公历1983-10-5转农历
* $lunar = new Lunar();
* $date = $lunar->getLar('1983-10-5',0);
*   echo date("Y-m-d", $date);
*   // 农历1983-8-29转公历
*   $date = $lunar->getLar('1983-8-29',1);
*   echo date("Y-m-d", $date);
*
* @param string 日期
* @param int    日期历法
*      - 0 公历
*        1 农历
*
* @return timestamp

这是一个国历与农历互相转的Unit.

其中年份皆用民国年份, 请自行转换 (西元年-1911 = 民国年).

* 前二数字 = 闰月月份, 如果为 13 则没有闰月                              *
* 第叁至第六数字 = 12 个月之大小月之2进位码->10进位                      *
* 例如:                                                                  *

*       1 : 代表大月(30天) 0 : 代表小月(29天) ==> 1月大2月小3月大..    *
* 第七位数字为闰月天数                                                   *
*           0 : 没有闰月之天数                                            *
*           1 : 闰月为小月(29天)                                          *
*           2 : 闰月为大月(30天)                                          *
* 最後2位数字代表阳历之1月1日与阴历之1月1日相差天数                      *

这对映表只有民国一年至民国一百年, 如不敷您的使用请按照上述之方式自行增加.

这个程式没有判断您所输入之年,月,日是否正确, 请自行判断.

如果转换出来之农历的月份是闰月则传给您的值是***负数***
如果农历要转换国历如果是闰月请输入***负数***

使用方法：

复制代码代码如下:

 $lunar = new Lunar();
   $date = $lunar->getLar('1983-10-5',0);
   echo date("Y-m-d", $date);
   // 农历1983-8-29转公历
   $date = $lunar->getLar('1983-8-29',1);
   echo date("Y-m-d", $date);
