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.

in fact if you use protected instead of private it works as expected
but the "private" issue should be clarified, i think
* i'm sorry for the second post

sure i know i don't need to override the method with the same one in the
new class to fix this problem
in the parent class the field is private... so theoretically i can not
access the member in the derived class
class A
{
private $a = "a";
}
class B extends A
{
private $a = "b"; // is this an error?
}
it probably is, and maybe php should throw an error
