I am trying to send email on codeigniter with attach file.

I always receive email successfully. However , I never receive with attach file. Below is code and highly appreciate for all comments.

```
    $ci = get_instance();
    $ci->load->library('email');
    $config['protocol'] = "smtp";
    $config['smtp_host'] = "ssl://smtp.gmail.com";
    $config['smtp_port'] = "465";
    $config['smtp_user'] = "test@gmail.com";
    $config['smtp_pass'] = "test";
    $config['charset'] = "utf-8";
    $config['mailtype'] = "html";
    $config['newline'] = "\r\n";

    $ci->email->initialize($config);

    $ci->email->from('test@test.com', 'Test Email');
    $list = array('test2@gmail.com');
    $ci->email->to($list);
    $this->email->reply_to('my-email@gmail.com', 'Explendid Videos');
    $ci->email->subject('This is an email test');
    $ci->email->message('It is working. Great!');

    $ci->email->attach( '/test/myfile.pdf');
    $ci->email->send();

```
