Finishing the Router
With the utility functions created and an autoloader in place to load the requested controller, the last step for
the router script is to actually handle the URI components that request the controller and ultimately send the
proper view to the user.
Loading the Controller
In index.php , add the following code between the initialization block and the function declarations:
// Registers class_loader() as the autoload function
// Loads and processes view data
// Parses the URI
$uri_array = parse_uri();
$class_name = get_controller_classname($uri_array);
$options = $uri_array;
// Sets a default view if nothing is passed in the URI (i.e. on the home page)
if (empty($class_name)) {
$class_name = 'Home';
