Bug #26737 (Protected and private variables are not saved on serialization when a user defined __sleep is used)
--FILE--
<?php
class foo
{
	private $private = 'private';
	protected $protected = 'protected';
	public $public = 'public';

	public function __sleep()
	{
		return array('private', 'protected', 'public');
	}
}
$foo = new foo();
$data = serialize($foo);
var_dump(str_replace("\0", '\0', $data));
?>
--EXPECT--
string(76) "O:3:"foo":3:{s:7:"private";N;s:9:"protected";R:2;s:6:"public";s:6:"public";}"
