    }//需要不同节日的，用不同的$config,然后配置$arr_lunar和$arr_solar
    $festivals = array();
    list($y,$m,$d) = explode('-',$today);
    if(!$nl_info) $nl_info = $this->convertSolarToLunar($y,intval($m),intval($d));
    if($nl_info[7]>0&&$nl_info[7]<$nl_info[4]) $nl_info[4]-=1;
    $md_lunar = substr('0'.$nl_info[4],-2).'-'.substr('0'.$nl_info[5],-2);
    $md_solar=substr_replace($today,'',0,5);
    isset($arr_lunar[$md_lunar])?array_push($festivals, $arr_lunar[$md_lunar]):'';
    isset($arr_solar[$md_solar])?array_push($festivals, $arr_solar[$md_solar]):'';
    $glweek = date("w",strtotime($today));  //0-6
    if($m==5&&($d>7)&&($d<15)&&($glweek==0))array_push($festivals, "母亲节");
    if($m==6&&($d>14)&&($d<22)&&($glweek==0))array_push($festivals,"父亲节");
    $jieqi = $this->getJieQi($y,$m,$d);
    if($jieqi)array_push($festivals,$jieqi);
    return implode('/',$festivals);
  }
}

调用方法：

$lunar = new Lunar();
$month = $lunar->convertSolarToLunar(date('Y'),date('m'),date('d'));
print_r($month);

运行结果：

Array
(
  [0] => 2017
  [1] => 闰六月
  [2] => 十七
  [3] => 丁酉
  [4] => 7
  [5] => 17
  [6] => 鸡
  [7] => 6
)
