PHP 實現西曆日期與農曆日期的互轉換

前言：

今天根據客戶的需求對時間進行了轉換，就是客戶要求增加農曆日期的顯示，在網上抄襲了一段，稍微修改了一下運行成功了，不難的，改動的很少的.

範例程式碼：

<?php /* *  * 陳海波   新二級頁面 農曆轉換成西曆 *  * */// lunar.php   建立這個php檔案，所有的代碼無需改，需要改的是下面teacher.php 的幾行class Lunar{  private $_SMDay = array(1 => 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);//定義西曆月分天數
