Description:
------------
get_object_vars() returns an array which can be manipulated as you would using a normal object. Manipulating the resulting array should not manipulate the object itself, but it does in this case.



Test script:
---------------
class Foo
{
  public $bar = null;
  public function __construct() {
    $this->bar = new DateTime(); // Now
    $this->far = &$this->bar;
  }
}
$foo= new Foo();
var_dump($foo);
$vars = get_object_vars($foo);
$vars['bar'] = new DateTime('2014-03-25');
var_dump($foo);


Expected result:
----------------
$foo->bar should not be altered, as we are only changing the get_object_vars() array, but it is.

Actual result:
--------------
$foo->bar (and $foo->far) gets a new value.
