php根據日期判斷星座的函數分享

復制代碼 代碼如下:
function yige_constellation($month, $day) {
 // 檢查參數有效性
 if ($month < 1 || $month > 12 || $day < 1 || $day > 31) return false;

 // 星座名稱以及開始日期
 $constellations = array(
  array( "20" => "寶瓶座"),
  array( "19" => "雙魚座"),
  array( "21" => "白羊座"),
  array( "20" => "金牛座"),
  array( "21" => "雙子座"),
  array( "22" => "巨蟹座"),
  array( "23" => "獅子座"),
  array( "23" => "處女座"),
  array( "23" => "天秤座"),
  array( "24" => "天蠍座"),
  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;
}

復制代碼 代碼如下:
echo yige_constellation(4, 20);
