Description:
------------
Defining an attribute within a method is possible even if it was not declared in the class.

This is some kind of hidden/ghost attributes ... if they have not been declared - e.g. public name etc. - it will be quite hard to understand a class using those "ghost attribute". Especially when the are defined in method bar() and later on used in method foo().

My system:
gentoo 2.4.26-gentoo-r9
apache 2.0.51-r1
PHP Version 5.0.3 / Zend Engine v2.0.3

Reproduce code:
---------------
<?php

class MyDestructableClass {
  function __construct() {
    $this->nev = "MyDestructableClass";
  }

  function show_nev()
  {
    print( '<br />nev is ' . $this->nev );
  }
}

$obj = new MyDestructableClass();
$obj->show_nev();

?>


Expected result:
----------------
There should be an Error messagen ( or at least a warning) saying: 

Use of undeclared attribute in ... on line ...

Actual result:
--------------
regarding my "example":

nev is MyDestructableClass
