$server=IoServer::factory(new HttpServer(new WsServer (new chat())) , 8080);
$server->run();
任何帮助,将不胜感激。
您是否尝试过声明'namespace'第一和设定,然后用'use'? http://php.net/manual/en/language.namespaces.importing.php我并没有真正使用命名空间,但手册似乎首先执行命名空间,然后使用'use'。 – Rasclatt
做得还是不错。 – shan2batman
你做了命名空间棘轮;'?你有包含'Ratchet'库的文件吗? – Rasclatt
