Can I ask one final clarification, please? Then the following should be koser in PHP 4 and 5, right? function &execute() { return new DB_result(); } Or would we need to do this to ensure proper opration in both versions? function &execute() { $tmp =& new DB_result(); return $tmp; } Or does the answer depend on what the constructor method does? Or...?
