陣列映射在PHP

Question

我具有兩個陣列說，

$array1 = array("code" => "E0089", 
       "desc" => "some description"); 

$array2 = array("code" => "Code", 
       "desc" => "Description"); 

所得陣列應，

$result = array("Code" => "E0089", 
       "Description" => "some description"); 

總之，我要地圖兩個陣列和創建第三陣列。

Answer 1

簡短：array_combine()

只是用這樣的：

$result = array_combine($array2, $array1); 

Answer 2

如果陣列已經在正確的順序：

$result = array_combine($array2, $array1); 

否則，你就需要做一些循環：

$result = array(); 
foreach ($array2 as $key => $val) 
    $result[$val] = $array1[$key];
