How can classes and autoloaders be used to improve the structure of PHP scripts?

Using classes and autoloaders can improve the structure of PHP scripts by organizing code into logical units, promoting reusability, and reducing the chances of naming conflicts. Autoloaders automatically load classes when they are needed, making it easier to manage dependencies and keep code clean.

// Autoloader function to load classes automatically
spl_autoload_register(function ($class) {
    include 'classes/' . $class . '.php';
});

// Example of using a class in a PHP script
$example = new ExampleClass();
$example->doSomething();
