Bug description:Access protected method violation
Description:
------------
In one case, the PHP engine allows access to the protected methods of an
instanciated class
As the documentation says : protected methods are only available inside the
class that declares it and inside the tree of derivated classes. If you
look at the code, we are in none of these case : $a is a standalone
instance of MyParent so the protected methods of class MyParent should be
hidden.
Am i wrong ?
Test script:
---------------
<?php
class MyParent {
protected function getProtectedParent() { return 'Parent_Protected'; }
}
class MyChild extends MyParent {
function getPublicChild() {
# --> new standalone instance of MyParent
$a = new MyParent();
# --> here it's possible to access to the protected method of $a !
return $a->getProtectedParent();
}
}
$cls = new MyChild();
$test = $cls->getPublicChild();
Expected result:
----------------
Fatal error : access level violation
Actual result:
--------------
$test = 'Parent_Protected'
