本篇章节讲解PHP编程实现阳历转换为阴历的方法。分享给大家供大家参考，具体如下：
php类

if($year==$this->MIN_YEAR&&$month<=2&&$date<=9) return array(1891,'正月','初一','辛卯','兔');
return $this->getLunarByBetween($year,$this->getDaysBetweenSolar($year,$date,$yearData[1],$yearData[2]));

}

}

调用方法：
convertSolarToLunar(date('Y'),date('m'),date('d'));
print_r($month);
运行结果：

[2] => 十七
[3] => 丁酉
[4] => 7
[5] => 17
[6] => 鸡
[7] => 6
