Bug description:Problem from array_diff function

Description:
------------
Hello, i have a problem from array_diff function. I have a two dynamic
arrays, which are a power from mysql. Which they have four different
values: 4415, 4416,4417, and 4418. Unfortunately, using this feature
(array_diff) has a bad output. (Return bad output)
Function returns the full contents of the first array Instead of a
difference.


Please inform me what may be wrong.

Regards, Dominik Koliński.

Test script:
---------------
This example from my code: 

	$query_select_id_1 = mysql_query("SELECT id FROM tabela1 where id <>
0") or die("Zapytanie niepoprawne"); 
	while($select_id_1 = mysql_fetch_assoc($query_select_id_1)){
		$array_1[] = $select_id_1['id'];
	}

	$query_select_id_2 = mysql_query("SELECT id FROM tabela2 where id <>
0") or die("Zapytanie niepoprawne"); 
	while($select_id_2 = mysql_fetch_assoc($query_select_id_2)){
		$array_2[] = $select_id_2['id'];
	}

$diff = array_diff($array_1, $array_2);
print_r($diff);
