Description:
------------
Behavor of array_diff is dependent on the sequence of the elements in
the array.
See $array2 where I changed the sequence of "a"=>"c" with "a"=>"d" and
it results in different output.
Be noted that the key of both elements is the same, still I would not
expect array_diff to take this into account.

Reproduce code:
---------------
// source 1
$array1 = array("a" => "c", "b" => "b" );
$array2 = array("a" => "c", "a" => "d" );
$result = array_diff($array1, $array2);
// source 2
$array1 = array("a" => "c", "b" => "b" );
$array2 = array("a" => "d", "a" => "c" );
$result = array_diff($array1, $array2);
Expected result:
----------------
// result1:
Array
(
[a] => c
[b] => b
)
// result2
Array
(
[b] => b
)
Actual result:
--------------
// for both I would expect
Array
(
[b] => b
)
