PHP Bug Type: Zend Engine 2 problem
Bug description: foreach enumerates private fields declared in base classes
Description:
------------
Using foreach on $this results in enumerating not only visible fields
(i.e. public and protected field declared along the inheritance hierarchy
+ private fields declared in current class) but also all private fields
declared along the inheritance hierarchy. This is wrong since those fields
are not visible and should not be accessible.
By the way, the foreach documentation page still says "foreach works only
on arrays...". Perhaps you should consider updating it ;-)
Reproduce code:
---------------
class A
{
private $c = "A's c";
}
class B extends A
{
private $c = "B's c";
public function go()
{
foreach ($this as $key => $val)
{
echo "$key => $val\n";
}
}
};
$x = new B;
$x->go();
Expected result:
----------------
c => B's c
Actual result:
--------------
c => B's c
c => A's c
