Description:
------------
When using the each() function on an object that contains private or protected properties I'm getting some unusual output shown below. 
I was wondering whether each() should be behaving the same as foreach() does (as shown in the documentation here: http://www.php.net/manual/en/language.oop5.iterations.php) and not be able to access private/protected properties, or whether like the next, prev and current functions, each() should not work with objects at all (bug raised here: http://bugs.php.net/bug.php?id=43480).

Reproduce code:
---------------
class myClass {
	private $val1 = 'hello';
	protected $foo = 'world';
	var $bar = 'baz';
}
$input = new myClass;

var_dump($input);

var_dump( each($input) );
var_dump( each($input) );
var_dump( each($input) );

Expected result:
----------------
array(4) {
  [1]=>
  string(3) "baz"
  ["value"]=>
  string(3) "baz"
  [0]=>
  string(3) "bar"
  ["key"]=>
  string(3) "bar"
}

Actual result:
--------------
array(4) {
  [1]=>
  string(5) "hello"
  ["value"]=>
  string(5) "hello"
  [0]=>
  string(13) " myClass val1"
  ["key"]=>
  string(13) " myClass val1"
}
array(4) {
  [1]=>
  string(5) "world"
  ["value"]=>
  string(5) "world"
  [0]=>
  string(6) " * foo"
  ["key"]=>
  string(6) " * foo"
}
array(4) {
  [1]=>
  string(3) "baz"
  ["value"]=>
  string(3) "baz"
  [0]=>
  string(3) "bar"
  ["key"]=>
  string(3) "bar"
}
