Are there potential issues with using frames in PHP applications, and what are some alternatives?

One potential issue with using frames in PHP applications is that it can make the code less maintainable and harder to debug. A better alternative is to use a modern PHP framework like Laravel or Symfony, which provide a more structured and organized way to build web applications.

// Example of using Laravel framework instead of frames in PHP applications
// Install Laravel using composer
composer create-project --prefer-dist laravel/laravel myapp

// Create a new controller
php artisan make:controller MyController

// Define routes in web.php
Route::get('/myroute', 'MyController@index');

// Implement the logic in the controller
public function index() {
    return view('myview');
}
