In the context of PHP MVC, what considerations should be made when deciding where to handle response generation and output formatting?

In PHP MVC, it is important to separate concerns and follow the principle of single responsibility. When deciding where to handle response generation and output formatting, it is recommended to handle this logic in the View layer. This helps keep the Controller focused on handling user input and business logic, while the View is responsible for presenting the data in the desired format. 

// Controller handling user input and business logic
class Controller {
    public function handleRequest() {
        // Handle user input and business logic
        $data = $this->getData();
        
        // Pass data to the View for output formatting
        $view = new View();
        $view->render($data);
    }
}

// View handling response generation and output formatting
class View {
    public function render($data) {
        // Output formatting logic here
        echo json_encode($data);
    }
}

// Usage
$controller = new Controller();
$controller->handleRequest();
