Maybe someone can help me find the array intersection of a multidemsional 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']);

Thanks for your help.

You could loop through the attributes array. – Michiel Pater Feb 25 '11 at 14:34

Do you have to find the intersection of all attributes or just color? – tandu Feb 25 '11 at 17:41
