What are the potential drawbacks of using a large Switch-Statement in PHP for handling web service requests?

Using a large Switch-Statement in PHP for handling web service requests can lead to code duplication, reduced readability, and difficulty in maintaining the code. To solve this issue, you can implement a more scalable and maintainable solution by using a routing system that maps requests to specific controller classes or methods based on the request URI. 

// Implementing a routing system in PHP to handle web service requests

// Define the routes and map them to controller classes or methods
$routes = [
    '/user' => 'UserController',
    '/product' => 'ProductController'
];

// Get the request URI
$requestUri = $_SERVER['REQUEST_URI'];

// Check if the requested route exists in the defined routes
if (array_key_exists($requestUri, $routes)) {
    // Instantiate the controller class based on the route
    $controller = new $routes[$requestUri]();
    
    // Call the appropriate method on the controller
    $controller->handleRequest();
} else {
    // Handle 404 Not Found error
    http_response_code(404);
    echo '404 Not Found';
}
