1.       What are the features of CakePHP?

  Flexible licensing

 Compatible with versions PHP 5.2.8 and greater

  Integrated CRUD for database interaction

  Application scaffolding

 Code generation

  MVC architecture

2.       What are Model, View and Controller?

The Model layer represents the part of your application that implements the business logic. It is responsible for retrieving data and converting it into meaningful concepts for your application.

The View renders a presentation of modeled data. Being separated from the Model objects, it is responsible for using the information it has available to produce any presentational interface your application might need.

The Controller layer handles requests from users. It is responsible for rendering a response with the aid of both the Model and the View layer.

3.       What are benefits of using CakePHP?

Ø  it is a tried and true software design pattern that turns an application into a maintainable, modular, rapidly developed package.

Ø  Crafting application tasks into separate models, views, and controllers makes our application very light on its feet.

Ø  New features are easily added.

Ø  The modular and separate design also allows developers to make changes in one part of the application without affecting the others.

3.      What functions of controller are used for request life-cycle callbacks?

beforeFilter(): This function is executed before every action in the controller.

beforeRender(): Called after controller action logic, but before the view is rendered.

afterFilter(): Called after every controller action, and after rendering is complete.

4.      What are the functions of set, render, redirect and flash methods?

The set() method is the main way to send data from controller to view.

The render() method is automatically called at the end of each requested controller action.

      The redirect(). This method takes its first parameter in the form of a CakePHP-relative URL.

     The flash() method is used to direct a user to a new page after an operation. The flash()   

     method is different in that it shows a message before passing the user on to another URL.

5.      Write the purpose of using $components, $helpers and $uses property?

Using these attributes make MVC classes given by $components and $uses available to the controller as class variables ($this->ModelName, for example) and those given by $helpers to the view as an object reference variable ($this->{$helpername}).

6.      What is scaffolding?

Scaffolding is a technique that allows a developer to define and create a basic application that can create, retrieve, update and delete objects. Scaffolding in CakePHP also allows developers to define how objects are related to each other, and to create and break those links.

7.      What is component?

Components are packages of logic that are shared between controllers. . They are useful when a common logic or code is required between different controllers.
