Why is the Codeigniter read file not working?

i am trying to show an image in a controller. it is now showing the image. this is what i tried to do. 1- Hardcode relative image path so that no confusion about the image 2- i put the piece of code in the constructor and it is working before "parent::__construct();" line. but it is not showing after this line.

class Fileupload extends Frontend_Controller
{
    function __construct()
    {
        //code is working here and showing image

        parent::__construct();

        //code below this line is not working

        $this->load->model('front_end/user_model');
        $dst_path = "C:\\xampp\htdocs\myweb\assets/uploads/avatar.jpg";
        header('Content-Type: image/jpeg');
        header('Content-Length: ' . filesize($dst_path));
        readfile($dst_path,true);
        die;
    }

any suggestion??

it look like you have some output in constructor. that is disturbing the code some space or something else. remove that space from constructor "Frontend_Controller" or use ob_clean(); before your code so that it

class Fileupload extends Frontend_Controller
{
    function __construct()
    {
        parent::__construct();

        ob_clean();// that will clean your browser.

        $this->load->model('front_end/user_model');
        $dst_path = "C:\\xampp\htdocs\myweb\assets/uploads/avatar.jpg";
        header('Content-Type: image/jpeg');
        header('Content-Length: ' . filesize($dst_path));
        readfile($dst_path,true);
        die;
    }

Please try this :

function __construct()
{
    //code is working here and showing image

    parent::__construct();

    //code below this line is not working

    $this->load->model('front_end/user_model');

    $dst_path = "C:/xampp/htdocs/myweb/assets/uploads/avatar.jpg";
    $data = file_get_contents($dst_path);
    $img = imagecreatefromstring($data);
    header("Content-Type: image/jpeg");
    imagejpeg($img);
    // die;
}

Or, please read this for more examples. :)

Write your code like this

<?php 
class Fileupload extends Frontend_Controller
{
  function __construct()
  {
      parent::__construct();
   }


 public function index() {
      $this->load->model('front_end/user_model');

      $dst_path   =   "C:\\xampp\htdocs\myweb\assets/uploads/avatar.jpg";

      header('Content-Type: image/jpeg');

      header('Content-Length: '  .  filesize($dst_path));

      readfile($dst_path,true);

   } 
}

?> The index function is always called by default in any MVC framework. This should help. Do try and tell
