CakePHP is a PHP web application framework that follows the Model-View-Controller (MVC) architectural pattern. In CakePHP, components are a way to package and reuse common functionality across controllers. Here are the steps to create and use components in CakePHP:

  1. Create a new file in the src/Controller/Component directory with the name of your component, e.g. MyComponent.php. The file should define a class that extends CakeControllerComponent.

// src/Controller/Component/MyComponent.php

namespace AppControllerComponent;

use CakeControllerComponent;

class MyComponent extends Component
{
    // Component code goes here
}


  1. Define the methods that your component will provide. Components can be accessed from controllers using the $this->MyComponent syntax.

namespace AppControllerComponent;

use CakeControllerComponent;

class MyComponent extends Component
{
    public function doSomething()
    {
        // Component method implementation
    }
}


  1. Add the component to your controller by including it in the $components array property.

namespace AppController;

use AppControllerAppController;

class MyController extends AppController
{
    public $components = ['My'];

    public function index()
    {
        $this->My->doSomething();
        // Controller code goes here
    }
}


  1. Use the component methods in your controller actions.

namespace AppController;

use AppControllerAppController;

class MyController extends AppController
{
    public $components = ['My'];

    public function index()
    {
        $this->My->doSomething();
        // Controller code goes here
    }
}


That's it! Now you can use the component in any controller that includes it in the $components array.
