Remove parent key in multidimensional array

Question

I would like remove key [Properties] from array like below

I have it:

Array(
 [Values] => 1
 [List] => Array(
     [Product] => Array( 
         [Details] => Array( 
            [Properties] => Array( 
                [Id] => 1
            )
         )
     )
  )
)

And I would like to remove [properties] :

Array(
  [Values] => 1
  [List] => Array(
    [Product] => Array( 
        [Details] => Array( 
            [ID] => 1
        )
     )
  )
)

I tried:

$result = array_map(function($sub) { return $sub['Properties']; }, $array);

and

$array= array_column($array, 'Properties');

Unfortunately it doesn't work. How can I do this ?

Can you edit your example input to show the structure when it has more than one entry? — Don't Panic

Straight-forwardly:

$arr = [
    "Values" => 1,
    "List" => ["Product" => [ "Details" => ["Properties" => ["Id" => 1] ] ] ]
];

$arr['List']['Product']['Details']['Id'] = $arr['List']['Product']['Details']['Properties']['Id'];
unset($arr['List']['Product']['Details']['Properties']);

print_r($arr);

The output:

Array
(
    [Values] => 1
    [List] => Array
        (
            [Product] => Array
                (
                    [Details] => Array
                        (
                            [Id] => 1
                        )
                )
        )
)
