Description:
------------
When an empty() call is done within a class that extends the MySQLi
class, an incorrect result is provided.

Reproduce code:
---------------
class Foo extends MySQLi
{
	protected $fooData = array();
	
	public function isEmpty()
	{
		$this->fooData[] = 'Bar';
		return empty($this->fooData);
	}
}

$Foo = new Foo('localhost', 'root', '', 'test');
$isEmpty = $Foo->isEmpty();

var_dump($isEmpty);

Expected result:
----------------
bool(false)

Actual result:
--------------
bool(true)
