//示例代码：
$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].\"月\".$today[2].\"农历\".$today[3].\"年\".$today[4].\"月\".$today[5].\"日\".$today[6].\"年<br/>\";
$month=$lunar->getJieQi(date(Y),date(m),date(d));//获取当前节气
echo \"今天节气：\".$month[name2];
?>
运行结果如下：
今天是公元2017年11月20日 今天是农历2017年十月月初三农历丁酉年11月3日鸡年 今天节气：立冬后
