What is the purpose of using MVC in PHP?

[gopi_27]

Hey, Anybody explain about Modular View Controller in PHP with a example. What are the special features of MVC.....

[DaveSawers]

Modular View Controller doesn't seem to be a part of PHP (at least it's not mentioned anywhere in the manual). A Google search on the phrase didn't return any useful results either.

So do you have any information on what it is more exactly?

Or do you mean Model View Controller? If so, doesn't the website contain all the information you need? http://www.phpmvc.net/

Hi,

Yes you are right MVC is not a part of PHP rather it is a concept of technique, you can find more about it at CodeProject: Using MVC to Unit Test WPF Applications. Free source code and programming help

MVC is the idea that you have three different pieces that work in unison to form a complex application. A car is a good real-world example of MVC. With a car you have two views: the interior and the exterior. Both take input from the controller: the driver. The brakes, steering wheel and other controls represent the model: they take input from the controller (driver) and hand them off to the views (interior/exterior) for presentation.

A model view controller could be considered an object or an array of values which sets the state for your application based on what it receives as input.

I'm not sure why terms model, view, controller are used specifically. I prefer the term routing.

Some features might include telling the application which libraries to load, who has permission to which sections, ect.

I do believe the primary purpose of it is to make people aware that it should be the core of your program. I think phpBB is a good example of an application with an extremely loose MVC... nothing is defined in the application itself (last I checked) but it's rather a consequence of how the files are organized.

While an application which passes everything through a single file and loads libraries and routes processes through it might be considered more rigidly defined as it's can be clear to everyone as to how the application actually works by looking at the code (array structures and objects) rather than sifting through it for a few months.


These are my own definitions... they are probably not the academically correct ones...
