Private enforces encapsulation, a key element of OOP. The current
behavior ensures you can extend the class without an effect on
show_private_member() and whatever happens in there. With your change
extending the class can hae an effect (by accident) on the method.

Could you please answer to my questions?

1) Answer for your question "Are you looking for protected elements?" is
"Bug #52245 Private member of parent class accessible from child
class."
2) Why you say that show_private_member() belongs to Parent class, if it
is inherited by its Child? In addition, I redefined the private member
in Child class - then, according to the paradigm of OOP polimoryizm, the
method should return a value of Child private member, otherwise all you
have said is contrary to OOP, in particular, to polymorphism.

You are calling show_private_member(). That method belongs to Father and
therefore has access to Father's private elements. The method has no
access to other class's private elements. Are you looking for protected
elements?

as for your code:
class A
{
private $a = "a";
}
class B extends A
{
private $a = "b"; // is this an error?
}
i think every class has own private member, so there is no error.

Ok, I got you.
I hope that this issue will be clarified.
Thank you for discussion.
