Bug Type: Arrays related
Operating System: linux 2.6.6
PHP Version: 5.0.0RC2
New Comment:
This problem apparently is in uasort. If you change uasort for, say,
uksort (and make code changes accordingly), the problem disappears.

Description:
------------
If you call uasort with one callback function and then call array_udiff
with another callback function, this last call will use first's
callback. If we first call array_udiff and then call uasort, everything
goes well.
Reproduce code:
---------------
<?
class p
{
public $x;
function __construct($x){$this->x=$x;}
}
function a(&$a, &$b){return $a->x - $b->x;}
function b(&$a, &$b){return $a->y - $b->y;}
$p1 = array(new p(2), new p(1), new p(0));
$p2 = array(new p(0), new p(2), new p(3));
uasort($p1, 'a');
print_r($p1);
echo "\n";
print_r(array_udiff($p1,$p2, 'b'));
?>
Expected result:
----------------
Notice: Undefined property: p::$y in tst.php on line 8
Actual result:
--------------
Array
(
[2] => p Object
(
[x] => 0
)
[1] => p Object
(
[x] => 1
)
[0] => p Object
(
[x] => 2
)
)
Array
(
[1] => p Object
(
[x] => 1
)
)
