Removing first array of multidimensional array - php

Question

I want to remove the first.. how to say that outside of the array and left inside array of a multidimension array. I couldn't found out the solution.. someone knows how to do it??
This is my code. I assign a array and i try to put into another array like this.
$final_sku = array();
foreach($skus as $sku){
foreach($sku as $key => $s){
$final_sku[] = array('Sku' => $s);
}
}
$newArray = array(
"Product" => array(
"PrimaryCategory" => "1",
"AssociatedSku" => "12",
"Attributes" => array(
),
"Skus" => $final_sku
)
);
And this is the $final_sku output be like.
[0] => Array
(
[Sku] => Array
(
[package_weight] => 5
[package_length] => 4
[package_width] => 3
[package_height] => 2
[package_content] =>
[tax_class] => default
[color_family] => Antique White
[price] => 4
[special_price] =>
[SellerSku] => sku1
[variation] => var1
)
)
[1] => Array
(
[Sku] => Array
(
[package_weight] => 5
[package_length] => 4
[package_width] => 3
[package_height] => 2
[package_content] =>
[tax_class] => default
[color_family] => Apricot
[price] => 4
[special_price] =>
[SellerSku] => sku2
[variation] => var1
)
)
I want the output be like this.
[Sku] => Array
(
[package_weight] => 5
[package_length] => 4
[package_width] => 3
[package_height] => 2
[package_content] =>
[tax_class] => default
[color_family] => Antique White
[price] => 4
[special_price] =>
[SellerSku] => sku1
[variation] => var1
)
[Sku] => Array
(
[package_weight] => 5
[package_length] => 4
[package_width] => 3
[package_height] => 2
[package_content] =>
[tax_class] => default
[color_family] => Apricot
[price] => 4
[special_price] =>
[SellerSku] => sku2
[variation] => var1
)
UPDATE: I want to pass the array and convert to xml. So the array key would be duplicated.

Answer 1

It does not make sense to have the same array of 2 members under the same key.
If you want to access one of them, what will be its uniqueness over the other?
The logical solution is
[sku] => [
0 => [first sku data....],
1 => [sku data....],
]
