php农历转公历怎么实现
php农历转公历的实现方法:首先获取一个PHP日期时间操作类“Lunar”;然后将“Lunar”相关代码保存为“Lunar.class.php”文件;最后使用“convertLunarToSolar();”方法实现农历转公历即可。

PHP 农历-阳历转换
分享一个实用的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:

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。
convertSolarToLunar(2014,2,12); //公历转农历 $date = $lunar->getYearZodiac(2014,2,12); //根据阴历年获取生肖 $date = $lunar->isLeapYear(2014,2,12); //判断闰年 //其它功能也是这种调用方法 print_r($date); //如果是农历转公历,代码如下: $date = $lunar->convertLunarToSolar(2014,2,12); //农历转公历 print_r($date); ?>
