插入一個數組導致多維arrray

Question

另一個陣列有兩個數組：

$arr1 = array 
(
    [0] => A 
    [1] => B 
    [2] => C 
    [3] => D 
) 

$arr2 = array 
(
    [0] => d 
    [1] => e 
    [2] => f 
) 

我想打一個多維數組會是這個樣子：

$arr3 = array 
(
    [0] => A => array 
      (
       [0] => d 
       [1] => e 
       [2] => f 
      ) 
    [1] => B 
    [2] => C 
    [3] => D 
) 

我想第一個數組的值應該是第二個數組的關鍵。

Answer 1

如果你想設置dynamicaly那麼你可以使用：

$arr3 = $arr1; 
$arr3[0] = array($arr3[0] => $arr2); 

Answer 2

這應該做的伎倆：

$arr3 = $arr1; 
$arr3[0] = array('A' => $arr2); 

Answer 3

$arr1 = array('A','B','C','D'); 
$arr2 = array('d','e','f'); 
$array = $arr1; 
$array[0] = array($arr1[0]=>$arr2); 
var_dump($array);
