php實現陽曆陰曆互轉的方法
阿新 • • 發佈：2018-12-25
最近對陽曆轉陰曆從而得到相應節日的演算法這方面比較感興趣，於是就在網上搜了一圈。不錯，還算是找到一個比較不錯的php類，實現了將陽曆轉換為陰曆（農曆），陰曆轉換為陽曆的演算法，同時還能獲取干支紀年，生肖，以及相應的陰曆的中文叫法等等，功能還是挺齊全的，在這裡分享給大家。
具體類程式碼如下：

使用方法如下：
header("Content-Type:text/html;charset=utf-8");
$lunar = new Lunar();
$month = $lunar->convertSolarToLunar('2018', '09', '25'); //將陽曆轉換為陰曆。注：這三個引數都必須是字串型別，否則會報錯
echo '<pre>';
print_r($month);
打列印結果如下：
