Summary: Private member of parent class accessible from child
class.
-Status: Open
+Status: Bogus
Type: Bug
Package: *General Issues
Operating System: Windows 7 x64
PHP Version: 5.3.2
New Comment:
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

.........
class Son extends Father{private $x = 'SON';
// try to decomment this:
//public function a(){echo $this->x;}
}
.............
I know if I override method a() in the child - everything will be ok,
but it's not necessary to override method a(), because method a() is
inherited form father class and it's public.
p.s. if it's a bug, then it's php behavior.

i think that is a bug but i'm not sure if is a php behavior
<?php
class Father{private $x = 'FATHER';
public function a(){echo $this->x;}
}
class Son extends Father{private $x = 'SON';
// try to decomment this:
//public function a(){echo $this->x;}
}
$son_instance = new Son;
$son_instance->a();
?>
