How to move Array up another level by key - php

Question

I have an array like below and what I want to achieve is basically remove the keys like #attributes and AddressSop and make them all one level so it removes the parent keys and array but keeps the key value pairs:
[Addresses] => Array
(
[0] => Array
(
[AddrCountry] => US
[AddrLine1] => Test Street
[AddrLine2] => Test
[AddrLine3] => Test
[AddrName] => Mr John Doe
[AddrEmail] => test#test.com
[AddrMasterPriceBook] =>
[AddrMobile] => 123132142242
)
[1] => Array
(
...
)
)
This is how the original array looks. Any help will be awesome thank you.
[Addresses] => Array
(
[0] => Array
(
[#attributes] => Array
(
[AddrCountry] => US
[AddrLine1] => Test Street
[AddrLine2] => Test
[AddrLine3] => Test
[AddrName] => Mr John Doe
)
[AddressSOP] => Array
(
[#attributes] => Array
(
[AddrEmail] => test#test.com
[AddrMasterPriceBook] =>
[AddrMobile] => 123132142242
)
)
)
[1] => Array
(
[#attributes] => Array
(
[AddrCountry] => US
[AddrLine1] => Test Street
[AddrLine2] => Test
[AddrLine3] => Test
[AddrName] => Mr John Doe
)
[AddressSOP] => Array
(
[#attributes] => Array
(
[AddrEmail] => test#test.com
[AddrMasterPriceBook] =>
[AddrMobile] => 123132142242
)
)
)
)

Try this:
foreach ($addresses as $key => $address) {
$addresses[$key] = array_merge($address['#attributes'], $address['AddressSOP']);
}
If you want it to be recursive, you can do something like this:
$filtered = [];
foreach ($addresses as $addressKey => $address) {
array_walk_recursive($address, function($val, $key) use(&$filtered, $addressKey) {
$filtered[$addressKey][$key] = $val;
});
}
print_r($filtered);
