最近对阳历转阴历从而得到相应节日的算法这方面比较感兴趣,于是就在网上搜了一圈。不错,还算是找到一个比较不错的PHP类,实现了将阳历转换为阴历(农历),阴历转换为阳历的算法,同时还能获取干支纪年,生肖,以及相应的阴历的中文叫法等等,功能还是挺齐全的,在这里分享给大家。
具体类代码如下:
lunarInfo[$year-$this->MIN_YEAR];
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],$yearData[2]));
}
function convertSolarMonthToLunar($year,$month){
$yearData=$this->lunarInfo[$year-$this->MIN_YEAR];
if($year==$this->MIN_YEAR&&$month<=2&&$date<=9){
return array(1891,'兔');
}
$month_days_ary=array(31,31);
$dd=$month_days_ary[$month];
if($this->isLeapYear($year)&& $month==2)$dd++;
$lunar_ary=array();
for ($i=1;$i<$dd;$i++){
$array=$this->getLunarByBetween($year,$i,$yearData[2]));
$array[]=$year.'-'.$month.'-'.$i;
$lunar_ary[$i]=$array;
}
return $lunar_ary;
}

使用方法如下:
PHP;">
convertSolarToLunar(2013,07,08);//将阳历转换为阴历
echo '
'; print_r($month);
