Sorry, it should be:
class F extends D
{
private function test() { } // stiffen visibility from public to private
(unexpected)
}
But nevertheless.

Description:
------------
It is possible to stiffen visibility (from public to protected, from public to
private and from protected to private) if any of parent classes has private
modifier.
Test script:
---------------
class A
{
private function test() { }
}
class B extends A
{
protected function test() { } // loosen visibility from private to
protected (expected)
}
class C extends B
{
private function test() { } // stiffen visibility from protected to
private (unexpected)
}
class D extends B
{
public function test() { } // loosen visibility from protected to public
(expected)
}
class E extends D
{
protected function test() { } // stiffen visibility from public to
protected (unexpected)
}
class F extends B
{
private function test() { } // stiffen visibility from public to private
(unexpected)
}
Expected result:
----------------
PHP Fatal error: Access level to C::test() must be protected (as in class B)
or
weaker
Actual result:
--------------
Everything is ok.
