PHP include paths
More of a general one this. I've got a bunch of classes that I use day to day. I've been playing with one of them, and I have tried to include another file at the top of the class containing some configuration options.
My path is like this:
/root/index.php
root/includes/class.inc.ph
root/includes/config.inc.p
So, the index includes the class, and the class includes the config.inc.php.
However, am I right in thinking, that for the class to include the config.inc.php, it will start the path from where *it* was originally called? i.e if my class file simply has include('config.inc.php');
What's the most flexible way around this?

if you want to include a file once use
require_once or include_once, so such a php-file is only included once, even if its called with require_once multiple times.
I typical have a fill which includes all nexessary thing e.g
config.php
<?php
// make settings
....
//include classes and function
require_once 'includes/class.inc.php';
require_once 'includes/class2.inc.php';
....
on the pages i use the only do a
require_once 'config.php';

That's kinda relying on knowing always the path, I guess what I'm after is a way of ensuring that the config file is called into the class file, always using the class file path.
you can also set your include_path directive in the php ini file such so that PHP searches for included files in the way that you want. You can do this in your script at runtime using ini_set():
http://us2.php.net/manual/en/function.ini-set.php
For information on include_path:
http://us2.php.net/manual/en/ini.sect.path-directory.php#ini.include-path
From the PHP manual:
Files for including are first looked in include_path relative to the current working directory and then in include_path relative to the directory of current script. E.g. if your include_path is ., current working directory is /www/, you included include/a.php and there is include "b.php" in that file, b.php is first looked in /www/ and then in /www/include/.

To this you just have to set up include path, where your includes reside like this
include_path=".:/root/incl
then you include those files just like if they were in root
include('config.inc.php');
That way your include will be the same no matter in what direcory file is.
