a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to

From manual page: http://www.php.net/function.array-uintersect#refsect1-
function.array-uintersect-description
---
array_uintersect (and other intersect-functions with callback) maybe link wrong..
the callback get some data a second time or nothing
or it gets 2 from the same array
Test script:
---------------
function compTest($first, $second)
{
echo "<br> first:".$first." second: ".$second;
if($first == $second) return 0;
return 1;
}
array_uintersect(range(1,3),range(1,3),"comptest");
<hr>
array_uintersect(range(1,2),range(4,5),"comptest");
Expected result:
----------------
1->1
1->2
1->3
and so on...
_____
1->4
1->5
2->4
2->5
Actual result:
--------------
first:2 second: 1
first:3 second: 2
first:2 second: 1
first:3 second: 2
first:1 second: 1
first:1 second: 2
first:2 second: 2
first:2 second: 3
first:3 second: 3
________
first:2 second: 1
first:5 second: 4
first:1 second: 4
first:1 second: 5
