Bug description: array_diff_assoc behaving different in PHP5 and PHP 4.3
Description:
------------
array_diff_assoc in PHP5 seems to ignore items whose values are objects.
This should be irrelevant as this function takes only keys as reference
for comparison. See code.
Reproduce code:
---------------
class Foo {
var $dato;
function Foo($dato) {
$this->dato = $dato;
}
}
$array1 = array ("a" => new Foo(5), "b" => new Foo(2), "c" => "azul",
"rojo");
$array2 = array ("a" => new Foo(5), "amarillo", "rojo");
$result = array_diff_assoc ($array1, $array2);
print_r($result);
Expected result:
----------------
PHP 4.3.8:
Output:
Array
(
[b] => foo Object
(
[dato] => 2
)
[c] => azul
[0] => rojo
)
Correct.
The same code with PHP 5.0.4:
Output:
Array
(
[a] => Foo Object
(
[dato] => 5
)
[b] => Foo Object
(
[dato] => 2
)
[c] => azul
[0] => rojo
)
which is not the same, and not correct in PHP5: [a] item should not be
there.
