wanted: array_diff for more than values

example: $arr1 = array("color" => "red", "flavor" => "cherry"); $arr2 = array("color" => "cherry", "flavor" => "red"); print_r(array_diff($arr1, $arr2)); those 2 arrays are different, but array_diff doesn't know it since it doesn't compare values at particular keys, just values in general. i want a function that knows that those 2 arrays are different; that the values for both color and flavor changed, and gives me back an array that looks exactly like $arr2. although it would take about five minutes to write such a function, i'm wondering, does one already exist and i just can't find it in the manual? thanks /nick
