How to merge multidimensional arrays where only subarrays are affected?

Question

here: Transforming array values in elements of a subarray using PHP I asked quite the same, but the arrays were flatter. I tried to adapt the code, but unfortunately without success.

How could I merge following arrays so the second array won't be added after the end of the first array, but each subarray of the first array will receive the correspondent values of subarrays of the second. In other words, I want to merge the subarrays. Here my example:

Array 01:

Array01 (

[0] => Array
    (
        [0] => 40292633
        [1] => 412
    )

[1] => Array
    (
        [0] => 41785603
        [1] => 382
    )

[2] => Array
    (
        [0] => 48792980
        [1] => 373
    )

[3] => Array
    (
        [0] => 44741143
        [1] => 329
    ))

Array 02:

Array02(

[0] => Array
    (
        [0] => 3460581
        [1] => 1407424B1
        [2] => 951753
    )

[1] => Array
    (
        [0] => 3484251
        [1] => 1028325B1
        [2] => 159357
    )

[2] => Array
    (
        [0] => 3519102
        [1] => 0586365A1
        [2] => 456654
    )

[3] => Array
    (
        [0] => 3529714
        [1] => 1059876A1
        [2] => 852258
    ))

Final array:

finalArray(

[0] => Array
    (
        [0] => 40292633
        [1] => 412
        [2] => 3460581
        [3] => 1407424B1
        [4] => 951753
    )

[1] => Array
    (
        [0] => 41785603
        [1] => 382
        [2] => 3484251
        [3] => 1028325B1
        [4] => 159357
    )

[2] => Array
    (
        [0] => 48792980
        [1] => 373
        [2] => 3519102
        [3] => 0586365A1
        [4] => 456654
    )

[3] => Array
    (
        [0] => 44741143
        [1] => 329
        [2] => 3529714
        [3] => 1059876A1
        [4] => 852258
    ))

Many thanks in advance!

try this code

function merge_arrays($a1, $a2) {

        return array($a1, $a2);
}

$result = array_map("merge_arrays", $a1, $a2);
foreach($result as $nr)
{
    $nres[] = array_merge ($nr[0], $nr[1]);
}
