Find if array exists in multidimensional array

Question

I have a multidimensional array that look like this:

Array


[1] => Array
    (
        [0] => ACURA
        [1] => CL
        [2] => 3.2L V6 F/I
        [3] => Blue
        [4] => 33-2133
        [5] => 33-2133
        [6] => V6
        [7] => F/I
        [8] => 
    )

[2] => Array
    (
        [0] => ACURA
        [1] => CL
        [2] => 3.2L V6 F/I
        [3] => Blue
        [4] => PS-1004
        [5] => PS-1004
        [6] => V6
        [7] => F/I
        [8] => 
    )

)

I then have another array that looks like

   Array
(
    [0] => ACURA
    [1] => CL
    [2] => 3.2L V6 F/I
    [3] => blue
    [4] => HP-1004
    [5] => HP-1004
    [6] => V6
    [7] => F/I
    [8] => 
)

Is the a way to look through the multdimensional array and see if the single array exists already in the multidimensional array?

I believe in_array() should work.

Link to PHP manual.

In the changlog it mentions that as of 4.2.0 the needle (search) can be an array...

This does not seem to work. I'm guessing because it can't search a multidimensional array. It always returns false.

@JasonSmall -- in_array is sufficient if you're only dealing with two dimensions.

@rdlowrey You are correct. I had the needle and haystack reversed.
