couldn't create own library

To create a library is very simple with CI. First you have to create a File with your Classname in your /application/library folder like

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Rufnex {

    function __construct($params)
    {
        $this->param = $params['test'];
        $this->ci =& get_instance();
    }

    public function hello()
    {
        echo "hello world";
    }

    public function load()
    {
        $this->ci->load->library('calendar');
        echo $this->ci->calendar->generate();
    }

    public function param($param)
    {
        echo "content of my param: ".$param;
        echo "<br />";
        echo "content of my class param: ".$this->param;
    }
    
} 


Then you can call your Class in you controller like this

PHP Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends MY_Controller {

    function __construct()
    {
        parent::__construct();
    }

    public function index()
    {
        $this->load->library('rufnex', array('test' => 123));
        $this->rufnex->hello();
        $this->rufnex->load();
        $this->rufnex->param('test');
    }
}
