in linux, the following array would be UNCHANGED after being put through array_unique.  But, in windows you'll see below, the it doesn't seem to go deeper into the value of each array element to check if they are the same or different.

the following are the results from using array_unique on wnidows 2000
BEFORE

Array
(
    [0] => Array
        (
            [0] => 4003
            [1] => 50140
            [2] => 1
        )

    [1] => Array
        (
            [0] => 4001
            [1] => 50140
            [2] => 1
        )

    [2] => Array
        (
            [0] => 2051
            [1] => 50200
            [2] => 1
        )

    [3] => Array
        (
            [0] => 998
            [1] => 50190
            [2] => 1
        )

)

AFTER ARRAY_UNIQUE

Array
(
    [1] => Array
        (
            [0] => 4001
            [1] => 50140
            [2] => 1
        )

)

Array_unique isn't supposed to handle multi-dimension arrays, nor objects.
