What are the advantages and disadvantages of using a PHP framework for development, especially in terms of learning and productivity?

Using a PHP framework for development can greatly improve productivity by providing a structured and organized way to build web applications. Frameworks like Laravel or Symfony also come with built-in features and tools that can save time and effort in coding. However, learning a new framework can have a steep learning curve and may require additional time and effort to master.

// Example of using Laravel framework to create a new route
Route::get('/example', function () {
    return view('example');
});
