CodeIgniter Tutorial: Use Pagination Class

Create a blogs table using sql below: 
CREATE TABLE `db_name`.`blog` (
    `blog_id` BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
    `title` VARCHAR( 200 ) NOT NULL ,
    `desc` TEXT NOT NULL ,
    `created` DATETIME NOT NULL ,
    `modified` DATETIME NOT NULL
) ENGINE = MYISAM

<?php
class blog extends Model
{
    function blog()
    {
        parent::Model();
        $this->load->database();
    }
    function count_blogs()
    {
        // Count total numbers of blog entries
        $query = $this->db->query('SELECT count(*) as count_blog FROM blogs');
        $result = $query->results();
        return $result[0]->count_blog;
    }
    function select_blogs($num, $offset)
    {
        // Fetch data from blogs table
        $query = $this->db->get('blogs', $num, $offset);
        $result = $query->results();
        return $result;
    }
}
?>

<?php
class blog extends Controller
{
    function blog() {
        parent::Controller();
        $this->load->library(‘pagination’);
        $this->load->model(‘blog’);
        $this->load->helper(‘url’);
    }
    function bloglist() {
        $config['base_url'] = ‘http://your-site.com/index.php/test/page/’;
        $config['per_page']=10;
        $config['total_rows'] =$data['count_blog'];
        $this->pagination->initialize($config);
        $data['title']=’CodeIgniter Pagination Example’;
        $data['bloglist'] = $this->blog->select_blogs($config['per_page'],$this->uri->segment(3));
        $data['count_blog']=$this->blog->count_blogs();
        // This will generate your pagination links
        $data['page_links']=$this->pagination->create_links();
        $this->load->view(‘blog/index’,$data);
    }
}
?>

<table>
    <?php for ($i=0; $i < count($bloglist); $i++) : ?>
    <tr>
        <td><?php echo $bloglist[$i]->title; ?></td>
    </tr>
    <tr>
        <td><?php echo $bloglist[$i]->desc; ?></td>
    </tr>
    <?php echo endfor; ?>
    <tr>
        <td><?php echo $page_links; ?></td>
    </tr>
</table>
