        {

          public function __construct()
          {
            $this->load->database();
          }

          public function get_news(){
            $query = $this->db->get['news'];
            return $query->result_array();
          }

        }

        ?>  

    my Controller

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

    class News extends CI_Controller {

      public function __construct (){
        parent::__construct();
        $this->load->model('news_model');
        $this->load->helper('url_helper');
      }

      public function index()
      {
        $data['news'] = $this->news_model->get_news();  
        $data['title'] = 'arsip';
        $this->load->view('news/index', $data);

    }
    ?>
my view
news/index.php

<?php
foreach ($news as $news_item) { ?>
  <h1><?php echo $news_item['title']; ?> </h1>
  //  <p><?php echo $news_item['text']; ?> </p>

Answer 1

change Your $this->db->get();

It's should not be array notation

  $this->db->get['news'];

it should be like

 $this->db->get('news');

alternatively u can use

  $this->db->select('*');
  $this->db->from('news');

  $query = $this->db->get();
  return $query->result_array()
