3) Create test.php under

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'root';
$db['default']['password'] = '';
$db['default']['database'] = 'test';

Example code:

        $user = new Users();
        $user->setUsername("jiansen");
        $user->setPassword("pass1");
        $data['message']= $user->login();
        echo '<tt><pre>' . $data['message'] . '</pre></tt>';
       
        //$this->load->view('magazines');
        echo '<h2>This is a test</h2>';
        $this->load->view('test',$data);
    }
}

?>
6) model users.php

<?php
Class Users extends CI_Model
{

    private $_username;

    function __construct()
    {
        parent::__construct();
    }
    public function setUsername($value)

    {
        $this->_password = $value;
    }
   public function login()
   {
        $this->load->database();
        $username = $this->_username;
        $password = $this->_password;
        $this -> db -> select('id, username, password');
        $this -> db -> from('users');
        $this -> db -> where('username', $username);
        $this -> db -> where('password', $password);
        $query = $this -> db -> get();
         if($query -> num_rows() == 1)
       {
           return "user name and pasword matched";
       }
       else
