WebsocketChat

Hi I am struggling to get this chat script to work, the only info I have been told is my server requires PCNTL Extension to run the chat script I was hoping someone is using a similar chat app in their site and can offer some help to get it running. It uses PHPSocket_IO the server.php uses

use Workerman\Worker; use Workerman\Lib\Timer; use PHPSocketIO\SocketIO; use App\Repositories\WebsocketChatRepository as chatRepo; use App\Models\ChatContact; use App\Models\Notifications; use App\Models\User; use App\Components\Plugin;
