这是一个实用的PHP日期时间操作类，里面包括了公历-农历转换、转换成中文日期格式、计算农历相隔天数、根据阴历年获取生肖、获取阴历月份的天数、获取农历每年的天数、获取闰月、计算阴历日期与正月初一相隔的天数、计算2个公历(阳历)日期之间的天数、根据距离正月初一的天数计算阴历日期、获取天干地支纪年等，PHP日期操作类：Lunar.class.php代码如下：
001
002class Lunar {
003 var $MIN_YEAR = 1891;
004 var $MAX_YEAR = 2100;

请将上面的代码保存为：Lunar.class.php，下面的例子将会调用这个文件，告诉你使用方法。
01
02require_once("Lunar.class.php");//先包含这个文件
03$lunar = new Lunar();//生成对象
04$date = $lunar->convertLunarToSolar(2014,2,12); //公历转农历
05$date = $lunar->getYearZodiac(2014,2,12); //根据阴历年获取生肖
06$date = $lunar->isLeapYear(2014,2,12); //判断闰年
07//其它功能也是这种调用方法
