How does autoloading functions in PHP impact performance and code organization in larger projects?

Autoloading functions in PHP can greatly improve performance by only including the necessary files when they are needed, reducing the overall memory footprint of the application. It also helps with code organization in larger projects by automatically loading classes or functions as they are called, making it easier to manage dependencies and keep the codebase clean.

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