What are some best practices for organizing folder structures and loading classes in PHP projects?

Organizing folder structures and loading classes in PHP projects is crucial for maintaining a clean and scalable codebase. One best practice is to use namespaces to organize classes into logical groupings and avoid naming conflicts. Additionally, autoloading classes using Composer's PSR-4 autoloader can simplify the process of loading classes without the need for manual require statements. 

// Autoload classes using Composer's PSR-4 autoloader
require_once 'vendor/autoload.php';

use App\Controllers\HomeController;

// Instantiate a class from the HomeController namespace
$homeController = new HomeController();
$homeController->index();
