Re: what happened to that new isset() like language

Marcus, my point was that this simple function: function ifsetor(&$var, $value) { return (isset($var)) ? $var : $value; } can be done in userspace, and that a coalesce() like function will have the added benefit of a variable number of parameters, which as far as I know, cannot be done in userspace, because call-by-reference cannot be done using func_get_args(). That was all, take it easy :) Ron "Marcus Boerger" <helly@php.net> wrote in message news:10757231.20051030104756@marcus-boerger.de... > Hello Ron, > > damn it! ifsetor or any equivalent cannot be done in userspace.
