class of objects created by mysqli_result->fetch_object

Hi, I fetched some data from my MySQL database into objects. These are of class stdClass. Now I wonder about the sense of having objects without methods defined. In fact, I cannot benefit from any of the OO advantages (namely property protection, controlled method calls on class properties) unless I wrap the properties of these instances of stdClass to a custom class, right? Is there any way to fetch MYSQL data to a suitable class other than stdClass - suitable in the sense of: the custom class has all properties which are fetched from db. thx Stefan
