Description:
------------
When using the each() function on objects, private and protected variables gets a NUL character around them (see expected result).

Create the test script and view it in a browser (I used Firefox 11.0). 

If you send an email with the output, the mail() function will just truncate the message after the NUL character

Test script:
---------------
class Foo
{
   public $a;
   protected $b;
   private $c;

   function bar($value) {
      echo $value;
   }
}

$tmp = new Foo();

while(list($key, $value) = each($tmp)) {
   var_dump($key);
}

Expected result:
----------------
string(1) "a"
string(4) "*b"
string(6) "Fooc"

Without the NUL character

Actual result:
--------------
string(1) "a"
string(4) "�*�b"
string(6) "�Foo�c"

� = NUL character, ASCII code (dec): 0
