Php implementation of the conversion of the Gregorian and lunar calendars

Recently, I was interested in the algorithm used to convert the Gregorian calendar to the lunar calendar, so I searched the internet. Yes, I found a pretty good php class. I realized the algorithm of converting the Gregorian calendar to the lunar calendar, and converting the Gregorian calendar to the Gregorian calendar. At the same time, I also got the algorithms, and the corresponding Chinese name of the lunar calendar. The functions are quite complete and we will share with you here.
The specific class code is as follows:

Class Lunar {var $ MIN_YEAR = 1891; var $ MAX_YEAR = 2100; var $ lunarInfo = array (,), array, 17,9584), array (,), array ), array (,), array, 16, 53856), array (,) 6), array (, rows 32), array ), array (,), array, 11,38320), array (,), array ), array (,), arra Y (,), array (,), array (), array, 26,27976), array (,), array ), array (,), array (, 1, 25, 43736), array (,), array, ), Array ), array (,), array, 8, 27296), array (6, 1, 28, 44368), array ), array (30,232,), array (,) 08), array (,), array ), array (,), array (6, 1, 28,), array (), array (,), array ), array (,), Rray (,), array (,), array, 10, 59984), array ), array (,), array (, 24, 54440), array (,), array, 9, 22176), array (,), array () ,), Array (), array ), array (,), array, 25, 29864), array ), array (, 17,42208), array (,) 4576), array (,), array ), array (,), array, 12, 46496), array (, rows), array ), array (,), array), Array (,), array (), array (,), array (,), array (6, 1, 28, 27216), array ), array (,), array, 26,23208), array (,), array (,), Array ), array (,), array (, 24, 48), array (, 12,), array (,), array, ), array ), array (,), array (, 30, 59696), array (,), array ), array (,), array )); /*** convert the Gregorian calendar to the Gregorian calendar * @ param year Gregorian calendar-year * @ param month Gregorian calendar-month * @ param date Gregorian calendar-day */function convertSolarToLunar ($ year, $ month, $ date) {// debugger; $ yearData = $ this-> lunarInfo [$ year-$ this-> MIN_YEAR]; if ($ year = $ this -> MIN_YEAR & $ month <= 2 & $ date <= 9) {return array (1891, 'july 1', '1n1', 'sinmao ', lunar January, rabbit);} return $ this-> getLunarByBetween ($ year, $ this-> getDaysBetweenSolar ($ year, $ month, $ date, $ yearData [1], $ yearData [2]);} function convertSolarMonthToLunar ($ year, $ month) {$ yearData = $ this-> lunarInfo [$ year-$ this-> MIN_YEAR]; if ($ year = $ this-> MIN_YEAR & $ month <= 2 & $ date <= 9) {return array (1891, 'October 11', '1e ', 'simmo', 'rabbit ');} $ month_days_ary = array (, 28, 31, 30, 31); $ dd = $ month_days_ary [$ month]; if ($ this-> isLeapYear ($ year) & $ month = 2) $ dd ++; $ lunar_ary = array (); for ($ I = 1; $ I <$ dd; $ I ++) {$ array = $ this-> getLunarByBetween ($ year, $ this-> getDaysBetweenSolar ($ year, $ month, $ I, $ yearData [1], $ yearData [2]); $ array [] = $ year.
