CakePHP is a web development framework written in PHP. The Controller component of CakePHP is responsible for accepting user requests and processing them to generate the needed output. A controller consists of several sections i.e. beforeFilters, components, and action methods.

BeforeFilters are like a global filter that runs before any controller action or component and it is used for doing any sort of preprocessing activities, like checking if an user is authenticated or authorizing an user for a resource.

Components are custom objects that are shared and are available across multiple controllers. Components are useful for functionality like authentication, pagination, email sending, etc., that are needed in multiple controllers but don't belong to any one controller.

Action methods in a controller consists of code written to take the user data, process it and generate the response in the form of a view file (like html) or sending an email.

For more information on CakePHP controllers and other topics, please refer to the CakePHP Documentation.

You can make fetch pagination from api in CakePHP using the RequestHandler component. Here's an example of the code in the controller to handle the paginated request:

php
 
 
Copy code
//Controller 

$this->loadComponent('RequestHandler'); 
$page = $this->request->query('page'); 

$numberPerPage = 10; 
$offset = ($page-1) * $numberPerPage; 

$data = $this->ModelName->find('all',[
    'limit' => $numberPerPage,
    'page' => $page,
    'offset' => $offset,
    'order' => 'ModelName.title ASC'
]);

$this->set(compact('data'));
$this->set('_serialize', ['data']);

You can find the official documentation for pagination in the CakePHP Cookbook here:
