php 公曆農曆如何實現轉換

php公曆農曆轉換的實作方法：首先建立PHP範例文件，並設定該文件的編碼為「utf-8」；然後引入「lunar.php」；接著透過「$lunar-> convertSolarToLunar()”方法將公曆轉換為農曆即可。

PHP實作陽曆(新曆)與陰曆(農曆)互相轉換 

使用方法：

convertSolarToLunar(2015,02,15);//将阳历转换为阴历
echo '
';
print_r($month);
?>
輸出結果：
Array
(
    [0] => 2014
    [1] => 腊月
    [2] => 廿六
    [3] => 甲午
    [4] => 13
    [5] => 26
    [6] => 马
    [7] => 9
)
