<?php
$dir=opendir(__DIR__);
while($files=readdir($dir)) {

But I get a few errors:

*Warning*: opendir(__DIR__) [function.opendir]: failed to open dir: No

in *C:\wamp\www\Project1\index.php* on line *2*

*Warning*: readdir(): supplied argument is not a valid Directory

__DIR__ is not a valid constant (yet, I think it may be planned for 
5.3/6). You should be developing with notices on - this would have told 
you __DIR__ is wrong.

Use dirname(__FILE__) to get what you're after.

maybe this is into coding standards and ethics.. but this may be acceptable:
if( !defined('__DIR__') ) {
  define('__DIR__' , dirname(__FILE__));
}

however realistically you'd have to do this in every file and nto just 
in one include, as it changes on a per directory basis; hence why it'd 
/need/ to be a *magic* constant I guess :)

talked myself in and out of that one; but yet still worth a post i fear!
