<?php
class foo {
private $foo = 'foo';
function printFoo1()
{
echo __CLASS__, ': ', $this->foo, "\n";
}
}
class bar extends foo {
protected $foo = 'bar';
function printFoo2()
{
echo __CLASS__, ': ', $this->foo, "\n";
}
}
class baz extends bar {
protected $foo = 'baz';
function printFoo3()
{
echo __CLASS__, ': ', $this->foo, "\n";
}
}
$bar = new baz;
$bar->printFoo1();
$bar->printFoo2();
$bar->printFoo3();
?>
Outputs:
foo: baz
bar: baz
baz: baz
When it should output:
foo: foo
bar: bar
baz: baz
Right?

you don't get the point, the problem is that baz's protected $foo
overrides foo's private $foo, that should not happen
using parent::foo() is a common technique, and there is a $this because
it get's the context of the calling point

Please, be more verbose next time if you want to get any help. Your
conciseness doesn't help very much.
The problem is that you're trying to access class members through $this
variable using static methods. As you can understand in this case there
is no $this and behavior seems to be undefined (shouldn't there be an
error, btw?).

Private members belong only to the class where they were defined and
cannot be inherited.

default value of protected member overrides default value of private
