【阴历转阳历】PHP实现农历阳历的相互转换(支持1900~2100年)

$yDiZhi=($yJiShu% 12==0)？10 :美元yJiShu % 12$ yganzhi=self :3360 Tian _ gan[$ ytiangan-1]。self :3360 di _ zhi[$ y dizhi-1]；////从0开始，所以我在这里再减去r

eturn $yGanZhi;
}

月的干支算法

网上搜索了, 没找到好的实现方式, 麻烦知道的在这里说一下,

日的干支算法

网上搜到的:

G = 4C + [C / 4] + 5y + [y / 4] + [3 * (M + 1) / 5] + d – 3
Z = 8C + [C / 4] + 5y + [y / 4] + [3 * (M + 1) / 5] + d + 7 + i
其中C 是世纪数减一，y 是年份后两位，M 是月份，d 是日数。1月和2月按上一年的13月和14月来算。奇数月i=0，偶数月i=6。G 除以10的余数是天干，Z 除以12的余数是地支。

但是不对, 麻烦有懂也告知下
