Question

有两个阵列：

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

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

我想创建一个看起来像这样的多维数组：

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

我猜第一个数组的值应该是第二个数组的键。

Answer 1

这应该可以解决问题：

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

Answer 2

如果您想设置dynamicaly，则可以使用：

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