這篇文章主要介紹了php實現的農歷算法,較為詳細的分析了農歷算法的原理與php實現技巧,非常具有實用價值,需要的朋友可以參考下

本文實例講述了php實現的農歷算法。分享給大家供大家參考。具體如下：

<?php

function lunarcalendar ($month, $year)

{

global $lnlunarcalendar;

/**

* Lunar calendar 博大精深的農歷

* 原始數據和算法思路來自 S&S

*/

/*

農歷每月的天數。

每個元素為一年。每個元素中的數據為：

[0]是閏月在哪個月，0為無閏月；

[1]到[13]是每年12或13個月的每月天數；

[14]是當年的天干次序，

[15]是當年的地支次序

*/
