获取密钥从多维指数

Question

我有以下阵列结构：

$CATEGORIES = array(
    array(
     category => "music", 
     color => "#FF8800" 
     ), 
    array(
     category => "film & TV", 
     color => "#59AF56" 
     ), 
    array(
     category => "culture", 
     color => "#fc2525" 
     ), 
    array(
     category => "science/tech", 
     color => "#5da9d4" 
     ) 
    ); 

基本上，类将一抬头，我需要检索的十六进制值。我找不到任何会为多维数组执行此操作（使用array_search（）尝试之后）。任何指针将不胜感激。

试试这个：

$category = 'culture'; 
foreach($CATEGORIES as $key){ 
    if($key['category'] == $category) 
     $hex = $key['color'];//here is your color 
}
