Upgrading an existing cubex project

Within your public/index.php you will need to upgrade

$cubex = new Cubex(dirname(__DIR__), $loader);
$cubex->handle(new Application());

to

use Cubex\Workerman\CubexWorker;

$worker = CubexWorker::create(
  dirname(__DIR__),
  $loader,
  function () { return new Application(); },
  'http://0.0.0.0:3000'
)->setCount(4);

this will run workerman on port 3000 with 4 processes
