Subject: Re: [PHP-DEV] unable to create class from constant
From: helly@php.net (Marcus Boerger)

Hello Jason,

  new doesn't expect a string which a constant in fact is. It expects a
class name. Thus the class name cannot be constified. You'd need to use
reflection for that:
$r = new ReflectionClass($name); $o = $r->newInstance();

best regards
