PHP Bug Type: Class/Object related
Bug description: Protected members of non-congruent children classes are
visible
Description:
------------
When you have two classes that extend the same base class, if the
protected members are declared in the base class, they are visible to each
other. Because the class variables are protected, they should not be
available to other classes, even if they share the same parent (but are of
different types themselves)!
Reproduce code:
---------------
<?php
class foo {
public $public = "a";
private $private = "b";
protected $protected = "protected";
}
class bar extends foo {
}
class kid extends foo {
public function test() {
$b = new bar();
var_dump(get_object_vars($b));
var_dump($b->protected);
}
}
$k = new kid();
$k->test();
Expected result:
----------------
array(1) {
["public"]=>
string(1) "a"
}
Visibility error.
Actual result:
--------------
array(2) {
["public"]=>
string(1) "a"
["protected"]=>
string(9) "protected"
}
string(9) "protected"
