[SOLVED] Get intersections of two items in a multidimensional array

Maybe someone can help me find the array intersection of a multidimensional array like this one:

[attributes] => Array
    (
        [Color] => Array
            (
                [0] => Cool White
                [1] => Warm White
            )
        [LED Amount] => Array
            (
                [0] => 30 LEDs
            )
    )
[FILTER] => Array
    (
        [Color] => Array
            (
                [0] => Warm White
            )
    )

I have tried the following code, but the problem is the multi-dimensional array.

$intersection = array_intersect($arry['FILTER'], $arry['attributes']);
