[Solved] Database Driven Config Question

I am working on a config file that I get my contents from database and set them in my config

application/config/setting.php

As you can see below I can require the database file fine,

Is there any way to be able to require codeigniter URI segments

Because currently I have to get segments like this  so would be better if I could use the url in my config file any ideas how to load url helper in my config file below 

cheers.

PHP Code:

$segments = explode('/', trim(parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH), '/'));
$numSegments = count($segments); 
$currentSegment = $segments[$numSegments - 3]; 


PHP Code:

<?php

$config = array();

require_once(BASEPATH . 'database/DB.php');

$db =& DB();

$db->where('type', 'config');
$query = $db->get($db->dbprefix . 'setting');

foreach ($query->result_array() as $result) {
    $config[$result['item']] = $result['value'];
}

$segments = explode('/', trim(parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH), '/'));
$numSegments = count($segments); 
$currentSegment = $segments[$numSegments - 3];

if ($currentSegment == 'admin') {
    $db->where('code', config_item('admin_language'));
} elseif ($currentSegment != 'admin') {
    $db->where('code', config_item('language'));
}

$lang_query = $db->get($db->dbprefix . 'language');

if ($query->num_rows() > 0) {
    $config['language']    = strtolower($lang_query->row()->name);
} else {
    $config['language']    = 'english';
} 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
