Description:
------------
When using get_class_vars() inside a class it does not act how it is documented on php.net. But that is not the main problem. It seems as if get_class_vars() is creating some strange identifiers in its resulting array, making it effictively unusable.

I already found out, that protected members are prefixed by '*' and private members are prepended with the classname, but the identifier-string is longer, than it should be.
When accessing my test-program with a web-browser there are some weird (probably multibyte) characters at the end of identifiers for protected and private members, which don't show up in a terminal using the CLI binary.

I'm not sure if this behaviour is expected (since it's not documented), but there would be no point in having get_class_vars() returning something that cannot be used subsequently.
And IMHO the Reflection-API behaves very differently; e.g. fetching class attributes in at least 5 lines (via Reflaction API) vs. a one-line call to fetch all attributes (via get_class_vars()).

Reproduce code:
---------------
class test {
    public $foo1;
    protected $foo2;
    private $foo3;
    public function __construct() {
        $this->foo1 = 'public';
        $this->foo2 = 'protected';
        $this->foo3 = 'private';
    }
}
$bar = array_keys(get_class_vars('test'));
var_dump($bar);


Expected result:
----------------
array(3) {
  [0]=>
  string(4) "foo1"
  [1]=>
  string(5) "*foo2"
  [2]=>
  string(8) "testfoo3"
}


Actual result:
--------------
array(3) {
  [0]=>
  string(4) "foo1"
  [1]=>
  string(7) "*foo2"
  [2]=>
  string(10) "testfoo3"
}
