How to Use CakePHP?
Assuming you have a basic understanding of PHP (if not, check out our introductory tutorial), using CakePHP is a piece of cake (pun intended). In this section, we’ll give you a quick rundown of the directory structure and some of the most important files in a CakePHP application. Then we’ll create a simple “Hello, World!” app to show you how everything fits together.
The first thing you need to do is download CakePHP. Once you have it on your local machine, unzip it into your web server’s document root directory. For this example, we’ll assume that your document root is /var/www/html . So if you unzipped CakePHP into your Downloads folder, you would move it like this:
$ mv ~/Downloads/cakephp-x.x.x /var/www/html/cakephp
Where x.x.x is the current version number. With that done, point your browser to http://localhost/cakephp , and you should see the Welcome page:
Understanding the MVC Architecture
The MVC architecture is a way of structuring code so that data, logic, and presentation are all separate. This makes code more modular and easier to maintain. In CakePHP, the Model represents the data, the View represents the presentation, and the Controller handles the logic.
CakePHP uses a convention-over-configuration approach, which means that it has default settings for everything. This makes it very easy to get started with CakePHP. However, it also means that you can easily change the defaults to suit your needs.
One of the advantages of using CakePHP is that it comes with built-in tools for validation, security, and caching. This can save you a lot of time and effort when developing your applications.
Using Controllers, Views, and Models in CakePHP
CakePHP is an open-source framework for PHP that provides an extensible architecture for developers to create web applications. CakePHP uses the Model-View-Controller (MVC) approach, which is a design pattern that separates the application’s data, presentation, and logic layers. This separation of concerns makes code more maintainable and reduces complexity.
The Model layer is responsible for interacting with data sources such as databases or APIs. Models are typically used to retrieve, insert, and update data. The View layer is responsible for generating the user interface (UI). Views are typically written in HTML, but they can also be generated using JavaScript or other client-side technologies. The Controller layer is responsible for handling user input and interactions. Controllers are typically the glue that binds the Model and View layers together.
In CakePHP, Controllers are classes that are located in the /app/Controller directory. Views are located in the /app/Template directory. Models are located in the /app/Model directory. The following diagram shows how these three components interact with each other:
When a user requests a page from a CakePHP application, the request is routed to a Controller. The Controller determines which action should be invoked based on the URL of the request. Once an action has been determined, the Controller will load any necessary Models and pass them to the View.
Working with Routes and Components
In any CakePHP project, you’ll need to work with both routes and components. Routes are responsible for matching URLs to controller actions, while components are building blocks that can be used in controllers to create more complex functionality.
Working with routes is relatively simple. In your project’s config/routes.php file, you’ll find an array of route objects. Each route object has a few different properties:
- ‘Pattern’ property is a regular expression that defines what URLs the route will match.
- ‘Controller’ property defines which controller should be used for matching URLs.
- ‘Action’ property defines which action method of the controller should be called.
You can also define additional parameters that will be passed to the controller action as well. For example, if you have a route like this:
$routes->connect(‘/posts/:id’, [‘controller’ => ‘Posts’, ‘action’ => ‘view’], [‘id’ => ‘\d+’]);
The :id parameter will be passed to the view() action method as an argument. You can access it in your code like this:
public function view($id) {
// Do something with $id…
}
Now let’s take a look at how components work. Components are classes that provide reusable functionality.
Understanding Database Connections in CakePHP
In CakePHP, a database connection is required to interact with your database. Connections are established in your config/database.php file using the following syntax:
‘Datasources’ => [
‘default’ => [
‘className’ => ‘Cake\Database\Connection’,
‘driver’ => ‘Cake\Database\Driver\Mysql’,
‘persistent’ => false,
‘host’ => ‘localhost’,
//’port’ => ‘non_standard_port_number’,
‘username’ => ‘my_app’,
‘password’ => ‘secret’,
‘database’ => ‘my_app’,
// // You can also add additional options like cache, encoding, etc.
],
// Other datasources…
// In general, each datasource defines its own set of parameters (e.g., className, driver, host). For more information on what each parameter means and how to configure your database connection, check out CakePHP’s documentation on Datasources.

With CakePHP you can also benefit from several powerful features like events & behaviors, localization & internationalization services and plugin architecture.
Q. Explain layers of CakePHP?
CakePHP works on MVC structure. MVC stands for the model view controller. MVC is an architectural pattern that describes a way to structure our application and explains the responsibilities and interactions of each part in that structure:
Model layer: This layer has business logic implemented for the application, such as retrieving data, converting or processing data, validating data that comes under this layer.
Controller layer: This layer is used to handle the request from the user. It gets requests from clients, checks its validity, fetches data accordingly, allocated resources, selects presentational data accordingly, and finally delegates the rendering process.
View layer: This layer is responsible for rendering the front-end interface from the information provided from the model data.
