In practice, it permits your web pages to contain minimal +scripting since the presentation is separate from the PHP scripting. + +- The **Model** represents your data structures. Typically your model + classes will contain functions that help you retrieve, insert, and + update information in your database. +- The **View** is the information that is being presented to a user. A + View will normally be a web page, but in CodeIgniter, a view can also + be a page fragment like a header or footer. It can also be an RSS + page, or any other type of "page". +- The **Controller** serves as an *intermediary* between the Model, the + View, and any other resources needed to process the HTTP request and + generate a web page. + +CodeIgniter has a fairly loose approach to MVC since Models are not +required. If you don't need the added separation, or find that +maintaining models requires more complexity than you want, you can +ignore them and build your application minimally using Controllers and +Views. CodeIgniter also enables you to incorporate your own existing +scripts, or even develop core libraries for the system, enabling you to +work in a way that makes the most sense to you. |
