});

$collector->post('products', function(){
return 'Create Product';
});

$collector->put('items/{id}', function($id){
return 'Amend Item ' . $id;
});

$dispatcher = new Phroute\Phroute\Dispatcher($collector->getData());

$response = $dispatcher->dispatch($_SERVER['REQUEST_METHOD'], parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH));

// Print out the value returned from the dispatched function

Can you try using exceptions to check these problems?

try {
    $response = (new Dispatcher($collector->getData()))->dispatch(
        $_SERVER['REQUEST_METHOD'],
        implode('/', array_slice(explode('/', $_SERVER['REQUEST_URI']), 0))
    );

echo($response);
} catch (HttpRouteNotFoundException $e) {
    echo($e->getMessage());
} catch (HttpMethodNotAllowedException $e) {
    echo($e->getMessage());
}
