title: How to autoload helper functions in codeigniter 4
body: <p>I just downloaded CodeIgniter 4 from their official GitHub. They changed a lot from CodeIgniter 3. I want to use <code>base_url()</code> function in the view and for that, you need to load URL helper and in CodeIgniter 3 I autoloaded it in <code>config/autoload.php</code> file. But now they have entirely changed the structure of <code>config/autoload.php</code> file in CodeIgniter 4 and it is very confusing to me.</p>
  
  <p>You can still use the <code>base_url()</code> function in your views in CodeIgniter 4 by using below code in your constructor of controller <code>helper('url');</code></p>
  
  <p>If anybody who used CodeIgnter 4 knows how to autoload helper functions like url by modifying <code>config/autoload.php</code> file please help me.</p>
