How do I use FastRoute?

Question

I\'m attempting to use the FastRoute routing library and can\'t get the simple usage example to work.

Here is the basic usage example found on the GitHub page:

Answer 1

I made a demo API that uses FastRoute and PHP-DI(dependency injection) to showcase how to use both. See: https://github.com/tochix/shapes-api/blob/master/src/Service/Http/Router.php#L94. In a nutshell, it looks like this:

/**
 * @param string $requestMethod
 * @param string $requestUri
 * @param Dispatcher $dispatcher
 * @throws DependencyException
 * @throws NotFoundException
 */
private function dispatch(string $requestMethod, string $requestUri, Dispatcher $dispatcher)
{
    $routeInfo = $dispatcher->dispatch($requestMethod, $requestUri);

    switch ($routeInfo[0]) {
        case Dispatcher::NOT_FOUND:
            $this->getRequest()->sendNotFoundHeader();
            break;
        case Dispatcher::METHOD_NOT_ALLOWED:
            $this->getRequest()->sendMethodNotAllowedHeader();
            break;
        case Dispatcher::FOUND:
            list($state, $handler, $vars) = $routeInfo;
            list($class, $method) = explode(static::HANDLER_DELIMITER, $handler, 2);

            $controller = $this->getContainer()->get($class);
            $controller->{$method}(...array_values($vars));
            unset($state);
            break;
    }
}
