PHP version: 5.2.5
PHP Bug Type: Class/Object related
Bug description: access to a private/protected property should not be allowed
Description:
------------
In some cases, PHP doesn't handle the visibility correctly, allowing a
private or protected member to be directly accessed via $obj->prop
This seems to happen when a class stores instances of itself and tries to
access their properties.
Reproduce code:
---------------
<?php
class bar
{
private $a;
private $children = array();
public function __construct($infiniteDepth)
{
$this->a = 'foo';
if ($infiniteDepth) $this->children[] = new self(false);
}
public function privateAcces()
{
foreach ($this->children as $child) {
echo $child->a; // here is the bug
}
}
}
$t = new toto(true);
$t->privateAcces();
Expected result:
----------------
fatal error as we access the private 'a' property from a non-$this context
Actual result:
--------------
the property gets read correctly, as if it was public
