PHP function to determine the zodiac sign based on a specific date

It seems to be quite popular to discuss zodiac signs now. The author below shares a function that uses PHP to determine which zodiac sign a specified date belongs to. The specific function code is as follows:

function constellation($month,$day){
	//检查参数有效性 http://www.phpernote.com/
	if($month<1||$month>12||$day<1||$day>31) return false;	
	//星座名称以及开始日期
	$constellations=array(
		array("20"=>"宝瓶座"),
		array("19"=>"双鱼座"),
		array("21"=>"白羊座"),
		array("20"=>"金牛座"),
		array("21"=>"双子座"),
		array("22"=>"巨蟹座"),
		array("23"=>"狮子座"),
		array("23"=>"处女座"),
		array("23"=>"天秤座"),
		array("24"=>"天蝎座"),
		array("22"=>"射手座"),
		array("22"=>"摩羯座")
	);
	list($constellation_start,$constellation_name)=each($constellations[(int)$month-1]);
	if($day<$constellation_start){
		list($constellation_start,$constellation_name)=each($constellations[($month-2<0)?$month=11:$month-=2]);
