Good. 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...?
