Info

CodeIgniter and classes. It is recommended to go through this user guide before building your first web app in CodeIgniter. Beside these three folders, there is one more important file named “index.php”. In this file, we can set the application environment and error level and we can define system and application folder name. It is recommended, not to edit these settings if you do not have enough knowledge about what you are going to do. 7
4. CodeIgniter – MVC Framework CodeIgniter CodeIgniter is based on the Model-View-Controller (MVC) development pattern. MVC is a software approach that separates application logic from presentation. In practice, it permits your web pages to contain minimal scripting since the presentation is separate from the PHP scripting. Figure: CodeIgniter – MVC Framework 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 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. 8
