[RESOLVED] MVC

lerro

I saw that in the MVC architecture, you separate the model, logic and view.

The concept seems to be that in

model - contains class and functions

controller - instantiates objects of classes and provides the logic

view - uses variables from controller and displays data to the user

What appears to be confusing is this, though i noticed that you can use a bit of logic in the view file (template) such as loops so as to display data, i still can't figure out why functions would be used in the logic file (controller).

I thought all functions should be in the model (class and functions) but it seems in the logic class, additional functions can be created.

Doesn't this create confusion?

It's really an "apples and oranges" thing. "Model", "view", and "controller" simply define areas of responsibility for a high-level breakdown of your application. "Class" and "function" are programming techniques that can be used for the implementation of any part of any application -- there is nothing prohibiting their use for any layer of the MVC structure.

Most MVC frameworks tend to use classes and possibly some separate stand-alone functions to implement both the models and controllers, and could also do so for the view, though it's more common to see procedural code/HTML for the view which may also make use of a library of functions and/or classes for output-related tasks.

There are many ways to to do MVC, PHP Frameworks.
There are also a whole bunch of opinions/definitions of what 'true' MVC is.
And what it should be like.

If we only stay to those frameworks in PHP using MVC
they all differ, sometimes very much, from eachother.
Probably depending on the person that developed/develops the MVC.
What that person thinks and likes to do in php coding.

True what NogDog tells. Most of them uses Classes for 90% of all tasks.
But the actual organizing of the web files & folders and how Classes depend on eachother
is very much, if not to say TOTALLY, different from MVC framework to framework.

I found this, perhaps the smallest MVC framework for PHP, yesterday.
After reading your first post:

TinyMVC-1.0.1.zip
25 kB

When you unzip it, it gets the enormous SIZE=51kB !!!!
It will probably do the basic work for a website.
Some say TinyMVC is a good starting of your own framework, in a web comment.
Because it may not handle too much 'junk'. So you will want to add your own features.

This latest version TinyMVC 1.0.1 is from Febr 18 2008. http://www.tinymvc.com/
Does not look as there is done some further developing.
