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 :) Andi At 12:05 PM 2/2/2004 -0500, Daniel Convissor wrote:

The following isn't: function foo() {

    $x = 1;
    return $x;

} function &bar() {

    return foo();

} Note: foo isn't returning by reference. 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...? ----- End forwarded message ----- -- T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y
