Re: Fwd: Re: [PHP-DEV] Only variables or references can be returned by reference

Without checking it more thoroughly, I think the former and the latter 
should work with both PHP 4 and PHP 5. If you want to be 100% certain then 
the latter will definitely work but I think we allowed the former in PHP 4 
too (in a hackish way).
Don't sue me if I'm wrong :)

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...?
