Merge Multidimensional Arrays

Question

I have a somewhat complicated function that builds an array structure dynamically to insert fields into MongoDB. We store the structure in MySQL.

The function outputs the following array structure:

Array
(
    [address] => Array
        (
            [street] => 10 Stack St
        )

)

Array
(
    [address] => Array
        (
            [city] => Overflow Mountains
        )

)
    Array
(
    [address] => Array
        (
            [state] => CM
        )

)
Array
(
    [address] => Array
        (
            [zip] => 01010
        )

)

I need to merge these arrays so it looks like

    [address] => Array
        (
            [street] => 10 Stack St
            [city] => Overflow Mountains
            [state] => CM
            [zip] => 01010
        )

How would I go about doing this? I am using PHP.

$result = array_merge($array1['address'], $array2['address'], $array3['address'], $array4['address']);

You can use array_replace_recursive().

Let your arrays be $array1, $array2, $arrray3, $array4

You can try

array_replace_recursive($array1, $array2, $array3, $array4);

Hope this helps
