* 公農歷轉換(1912 - 2012)
*
* Usage:
* // 公歷1983-10-5轉農歷
* $lunar = new Lunar();
* $date = $lunar->getLar('1983-10-5',0);
* echo date("Y-m-d", $date);
* // 農歷1983-8-29轉公歷
* $date = $lunar->getLar('1983-8-29',1);
* echo date("Y-m-d", $date);
*
* @param string 日期
* @param int 日期歷法
* - 0 公歷
* 1 農歷
*
* @return timestamp
這是一個國歷與農歷互相轉的Unit.
其中年份皆用民國年份, 請自行轉換 (西元年-1911 = 民國年).
***************************************************************************
*國農歷對映表之說明 : *
***************************************************************************
* 前二數字 = 閏月月份, 如果為 13 則沒有閏月 *
* 第三至第六數字 = 12 個月之大小月之2進位碼->10進位 *
* 例如: *
* 101010101010 = 2730 *
* 1 : 代表大月(30天) 0 : 代表小月(29天) ==> 1月大2月小3月大.. *
* 第七位數字為閏月天數 *
* 0 : 沒有閏月之天數 *
* 1 : 閏月為小月(29天) *
* 2 : 閏月為大月(30天) *
* 最後2位數字代表陽歷之1月1日與陰歷之1月1日相差天數 *
***************************************************************************
這對映表只有民國一年至民國一百年, 如不敷您的使用請按照上述之方式自行增加.
這個程式沒有判斷您所輸入之年,月,日是否正確, 請自行判斷.
如果轉換出來之農歷的月份是閏月則傳給您的值是***負數***
如果農歷要轉換國歷如果是閏月請輸入***負數***
此版本為FreeWare Version : 0.1
您可以自行修改, 但最好可以將修改過之程式Mail一份給我.
如果您要用於商業用途, 請mail給我告知您的用途及原因.
