Passing a config file into a custom library codeigniter

So I was reading in the Codeigniter user guide and they say that:

You can also pass parameters stored in a config file. Simply create a config file named identically to the class file name and store it in your application/config/ folder. Note that if you dynamically pass parameters as described above, the config file option will not be available.

I have a config file set up with the identical name as my library and I am wondering how I can access the contents of that file. Do I need to load the config before loading the lib? Do all of the variables need to be elements of an array?

examples:

-- Config file --

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$var1 = "Variable 1";
$var2['name'] = "foo";
$var2['title']= "bar";
$var2['content'] = "Lorem ipsm dolar sit imut";

-- Library file --

class Library 
{
    var $data;
    function __construct($data)
    {
            $this->data = $data;
    }
}

-- Then something along the lines of --

function __construct() {
    parent::__construct();
    $this->load->library("library");
}
function index()
{
    var_dump($this->library->data);
}

(Yes I figure the name Library is reserved but this is an example)

Shouldn't the var_dump simply dump the contents of the config file? What am I doing wrong?

Few things to make this work :

Your classname FILE should start with a capital letter, Your config array must be defined as $config = array() (and not $var or any other name), Your config file must be lowercase.

The config file is passed through the constructor, so class($config=array()), you can then access and store the config variables on an instance variable.

hope it helps:

class Foo // Foo.php
{
    function __construct($config=array())
    {
        $this->config = $config;
    }

} //end of class

config file:

$config['url'] = 'stuff'; // config file : foo.php

good luck :)

To access the variables of config file in your custom library, you can initialize a new CI instance and access the content of config like below:

$this->ci = & get_instance();

$configs = $this->ci->config;

Now do var_dump($configs) to see content of config file.
