How can autoloading be used to include classes in PHP?

Autoloading in PHP allows classes to be automatically included when they are needed, without the need to explicitly include them in every file. This can help streamline the code and make it more organized. To implement autoloading, you can use the spl_autoload_register() function to register a function that will load the class files when they are needed. 

spl_autoload_register(function($class_name) {
    include $class_name . '.php';
});

// Now when a class is used but not yet included, it will be autoloaded
