Bug #66961 [NEW]: get_object_vars() returns object references
From: thomas dot stavang dot pedersen at gmail dot com
Operating system: Linux, Fedora 19
PHP version: 5.5.10
Package: Unknown/Other Function
Bug Type: Bug
Bug description:get_object_vars() returns object references
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.
