Correcting my MVC concept

[cssniper]

I am a little confused with the MVC concept of programming. I know what it means and and all that, but I am not sure that I completely grasped it. Please correct me if I am wrong:

 

Example: User Authenicating system (UAS).

 

./index.php - This file selects the controller, specifying which model to execute.

 

./controllers/users.php - This file is the module file of the UAS. By taking information from ./index.php, it executes the correct model. It also receives information from the model and calls the appropriate view.

 

./models/users/ - Contains Model files for the UAS module. eg. registration.php, login.php. Main logics lies in these scripts.

 

./views/ - Contain view files.
