从多维数组PHP剥离层

Question

I am having some difficulty manipulating the below array. I have tried various things and I feel like there should be a simple way to achieve this, but I cannot seem to figure it out. Any tips or help greatly appreciated, thanks!

        Array
    (
        [0] => Array
            (
                [0] => Array
                    (
                        [Color] => Blue
                    )

                [1] => Array
                    (
                        [Size] => S
                    )

            )

        [1] => Array
            (
                [0] => Array
                    (
                        [Color] => Blue
                    )

                [1] => Array
                    (
                        [Size] => M
                    )

            )
)

My desired outcome is:

        Array
    (
        [0] => Array
            (
                  [Color] => Blue
                  [Size]  => S
            )

        [1] => Array
            (
                  [Color] => Blue
                  [Size] => M        
            )
)

This works:

$items = array(
    array(
        array("Color" => "Blue"),
        array("Size" => "S")
    ),
    array(
        array("Color" => "Blue"),
        array("Size" => "M")
    )
);
$new_items = array();
foreach ($items as $item) {
    $collect = array();
    foreach ($item as $values) {
        foreach ($values as $key => $value) {
            $collect[$key] = $value;
        }
    }
    $new_items[] = $collect;
}
var_dump($new_items);

Your array is 3 deep, so you need at least 3 nested loops.

Output:

array(2) {
  [0]=>
  array(2) {
    ["Color"]=>
    string(4) "Blue"
    ["Size"]=>
    string(1) "S"
  }
  [1]=>
  array(2) {
    ["Color"]=>
    string(4) "Blue"
    ["Size"]=>
    string(1) "M"
  }
}
