Reported By: andreigurin at tiscali dot it

Operating System: windows xp sp2 / linux centos /
PHP Version: 4.4.2
New Comment:

your test results :

Fatal error: Using $this when not in object context..

and the code you mention cannot run in PHP4, since PHP doesn't have
public, private modifiers...

what are you talking about ?

Description:
------------
$this keyword visibility is violated if accessed from a function
external to a class. This happens in 4.*** versions, and in 5.***,
Tested on Window 2000, Windows Xp sp2, Linux Centos(3.7?), Red hat, and
some other Linux based systems

Reproduce code:
---------------
class Foo {
private $__prv;
public function __constructor($v) {
$this->__prv = $v;
}
public function do_something() {
bla bla bla...
hack();
}
public function prv() {
return $this->__prv;
}
}
function hack() {
$this->__prv = 'A very bad value!';
}
$foo = new Foo('A good __prv value');
$foo->do_something();
print $foo->prv();

Expected result:
----------------
Triggered error:
bla bla bla undefined variable this in file.php on line ...
Output:
A good __prv value

Actual result:
--------------
Output:
A very bad value
