这篇文章主要介绍了php实现的农历算法,较为详细的分析了农历算法的原理与php实现技巧,非常具有实用价值,需要的朋友可以参考下,本文实例讲述了php实现的农历算法,分享给大家供大家参考,具体如下:
- <?php
- function lunarcalendar ($month, $year)
- {
- global $lnlunarcalendar;
- /**
- * Lunar calendar 博大精深的农历
- * 原始数据和算法思路来自 S&S
- */
- /*
- 农历每月的天数。
- 每个元素为一年。每个元素中的数据为:
- [0]是闰月在哪个月,0为无闰月;
- [1]到[13]是每年12或13个月的每月天数;
- [14]是当年的天干次序,
- [15]是当年的地支次序
- */
- $everymonth = array(
