上午在做一个用户的定制时,需要获取到当天的农历日期,以及节气。网上找了一个php代码写的农历日期与公历日期相互转换的类,并优化和修改了一下,测试可以正常使用的。发出来,有需要的可以拿去哦。

6、输出阳历月分的天数

7、输出阴历月分的天数

8、输出农历的节气

9、输出时辰

类的使用方法

1、phpi输出当前的农历日期

<?php
$lunar = new Lunar();
$today = $lunar->convertSolarToLunar(date("Y"),date("m"),date('d'));
//echo "今天是公元".date(Y)."年".date(m)."月".date(d)."日<br/>";
echo "今天是农历".$today[0]."年".$today[1].$today[2];
echo '<br/>';
echo "今天是农历".$today[3]."年".$today[4]."月".$today[5]."日";
echo '<br/>';
echo '今年是生肖:'.$today[6]."年";
?>

输出结果:
