New Comment:
May be this should be noticed in the manual, because it's not clear
what does mean "also works on objects".

ARRAY_key_exists() first converts it to ARRAY and then continues
working, which is expected.

Description:
------------
array_key_exists() may take object as second parameter and
in such case I think it should use __isset() magic function of the
object (if any), but it seems not to do so.
The isset() and array_key_exists() may return different results for
the same object, which is not good :)
Reproduce code:
---------------
class TestObject
{
function __isset($nm)
{
return true;
}
}
$A = new TestObject();
var_dump(array_key_exists('test', $A));
var_dump(isset($A->test));
Expected result:
----------------
true
true
Actual result:
--------------
false
true
