How can I use MVC ideas without using classes?

As of right now, I am still shaky on classes, so I don't want to use any classes for my site. I'm still practicing with classes.

But how can I implement the MVC idea without classes?

Would this work for a MVC?

index.php (the view)

index_controller.php

index_model.php

    Is this开发者_如何学Python right for what a MVC should be? 
View: show html, css, forms 
Controller: get $_POST from forms and any data from the user, get info from db 
Model: do all the functions, insert/delete in db, etc

Basically separate the HTML/css for the view, all the data collecting for the controller, and the logic for the model. And just connect them all using require_once.

Controller: Your index.php, accepting and directing requests. This can certainly be a 'classless' script. It would act as both controller and 'front controller'.

View(s): A collection of presentation scripts, specific script included by your controller. Essentially 'getting' data from the variable scope of the controller.

Model(s): A collection of functions that provide access to your data. The controller determines what to include for a request.

Sure, it can be done, but you loose a lot not using classes (OOP). Here's a quick example of what the controller might look like. Nothing amazing, just an idea. Showing the controller should shed some light on the model/view as well.

<?php
  $action = getAction(); //parse the request to find the action
  switch($action){
    case 'list':
      include('models/todolist.php'); //include the model
      $items = todolistGetItems(); //get the items using included function
      include('views/todolist/list.php'); //include the view
      break;
    case 'add':
      if(!empty($_POST['new'])){ 
        include('models/todolist.php'); //include the model
        todolistAddItem($_POST); //add the item
        $items = todolistGetItems(); //get the items using included function
        include('views/todolist/list.php'); //include the view
      } else {
        include('views/todolist/add.php'); //include the view
      }
  }
