The check whether a class property/method is accessible is based on the
class of the scope you're in. It's not based on the instance. Note that
encapsulation is still conserved as private properties are accessible only
from methods of the class they're defined in. It also allows you to work
with static methods that access private properties.

3. Is it a bug that i can't use same property name in my child class?

I'm not sure what you mean. As you can do:

class A { private $foo = 2; }
class B extends A { private $foo = 3; public function foo() { echo
$this->foo; } }
$b = new B; $b->foo(); // 3


Thats just some questions :)
