Bug description: property_exists() fails to find protected properties from a
parent class
Description:
------------
When using property_exists() from a parent class, and checking for the
existence of a protected property in the subclass, property_exists() fails
to find the property.
The documentation for property_exists() says that the property must be
'accessible from the current scope'. In this case, the property _is_,
because A is a parent class and protected visibility is defined in the
documentation as 'limits access to inherited and parent classes'.
As further evidence that protectedBar is accessible from foo(), trying to
manipulate privateBar causes an error, while manipulating protectedBar
doesn't.
Reproduce code:
---------------
<?php
class A {
function foo() {
var_dump(property_exists('B', 'publicBar'));
var_dump(property_exists('B', 'protectedBar'));
var_dump(property_exists('B', 'privateBar'));
}
}
class B extends A {
public $publicBar;
protected $protectedBar;
private $privateBar;
}
$b = new B();
$b->foo();
Expected result:
----------------
bool(true) bool(true) bool(false)
Actual result:
--------------
bool(true) bool(false) bool(false)
