php根据日期判断星座的函数

 下面提供一个用PHP来判断指定一日期属于哪个星座的函数,需要的朋友可以参考下

 代码如下:

function yige_constellation($month, $day) {

 // 检查参数有效性 

 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]);

 

 return $constellation_name;

}

 

 

调用示例：

 

 代码如下:

echo yige_constellation(4, 20);
