-Status: Open
+Status: Bogus
Bug Type: Class/Object related
Operating System: windows xp sp2 / linux centos /
PHP Version: 4.4.2
New Comment:
It's not related to public/private modifiers at all.
Static methods which were not declared as static inherit $this from the
parent scope.
This is the only way to preserve backward compatibility with PHP4 and
it won't change in PHP5.

sorry, here is the php 4 code
<?php
error_reporting(E_ALL);
class Foo {
var $__prv;
function Foo($v) {
$this->__prv = $v;
}
function prv() {
return $this->__prv;
}
function tst() {
Bar::babar();
}
}
class Bar {
function babar() {
$this->__prv = 'a very very bad value';
print $this->prv();
}
}
$foo = new Foo('PRV VALUE');
$foo->tst();
?>

Well, IMHO, such a behavior is violating the basics of OOP...
Documentation is missing(am I right?). This is a BUG (a feature???
mmm...). In php4 (private & public modifiers missing), you may access
every object field...
<?php
error_reporting(E_ALL);
class Foo {
protected $__prv;
public function Foo($v) {
$this->__prv = $v;
}
public function prv() {
return $this->__prv;
}
function tst() {
Bar::babar();
}
}
class Bar {
public function babar() {
$this->__prv = 'a very very bad value'; /* IS IT OK???!!!*/
print $this->prv();
}
}
$foo = new Foo('PRV VALUE');
$foo->tst(); /* $foo->__prv is modified now!!!*/
?>

Are there a piece of documentation describing this behavior? Thanks for
reply!

This is expected and it was done in order to keep compatibility with
4.x.

ok, try this
<?php
error_reporting(E_ALL);
class Foo {
protected $__prv;
public function Foo($v) {
$this->__prv = $v;
}
public function prv() {
return $this->__prv;
}
function tst() {
Bar::babar();
}
}
class Bar {
public function babar() {
print $this->prv();
}
}
$foo = new Foo('PRV VALUE');
$foo->tst();
?>
