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 :)
