Bug description: Wrong private method virtual behaviour
Description:
------------
When a private method is overriden and the visibility is increased to
public or protected, then this method loses its non-virtual behaviour in
methods of classes where the method is private.
So in the example bellow ext2::abc is called instead of base::abc and
ext::abc. Also when the function prototype is different warning appear.
Reproduce code:
---------------
class base {
public function test() { $this->abc(); }
public function test2() { $this->abc(); }
private function abc() { echo "base::abc<br/>"; }
}
class ext extends base {
public function test2() { $this->abc(null); }
private function abc ($param1) { echo "ext::abc<br/>"; }
}
class ext2 extends ext {
protected function abc ($param1, $param2) { echo "ext2::abc<br/>"; }
}
$base = new base();
$base->test(); $base->test2();
$ext = new ext();
$ext->test(); $ext->test2();
$ext2 = new ext2();
$ext2->test(); $ext2->test2();
Expected result:
----------------
base::abc
base::abc
base::abc
ext::abc
base::abc
ext::abc
Actual result:
--------------
base::abc
base::abc
base::abc
ext::abc
