How can PHP autoloading or includes be used to improve routing and avoid redirection issues?

When working with PHP applications, autoloading or including files can help improve routing by dynamically loading classes or files as needed, reducing the need for manual includes and improving code organization. This can also help avoid redirection issues by ensuring that the necessary files are loaded in the correct order.

spl_autoload_register(function($class){
    include 'classes/' . $class . '.php';
});

// Example usage
$router = new Router();
$router->route();
