Insert one array into another array resulting multidimensional arrray

Question

There are two arrays:

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

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

I want to make a multidimensional array that would look something like this:

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

I guess first array's value should be the key of the second array.

This should do the trick:

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

Yes, it does a trick. Though like this $arr3[0] = array($arr3[0] => $arr2) no need to know a value of first array's selected position. Thanks man!

If you want to set dynamicaly then you can use:

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

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