Question

当我的websocket服务器处理连接时，我正在使用线程来运行异步任务。该线程通过套接字连接到另一个打开的服务器。

当客户端连接到Websocket时，套接字调用此类中的一个函数，该函数向所有连接的客户端发送消息。当线程检索消息时，它将调用相同的函数。

我的问题是，当线程调用此函数时，websocket不会向所有连接的客户端发送消息。即使我在类的实例上调用该函数，所有客户端保存到的变量在两个函数调用中也不同。

我曾经尝试将clients变量作为参数添加到函数中，并使用getters和setters并将其公开。一切都得到相同的结果。

<?php
set_time_limit(0);

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
require_once 'vendor/autoload.php';

class WorkerThread extends Thread {
    private $connection;
    public $msgHistory;

    public function __construct($connection) {
        $this->connection = $connection;
        $this->msgHistory = array();
    }

    public function run() {
        while (true) {
            // Socket reader would be here

            $msg = "test";

            // Add to message history
            $this->msgHistory[count($this->msgHistory)] = $msg;

            // Send message to all clients
            $this->connection->sendMessageToAllClients(array($msg), false); // Function displays "Connection count: 0"
            }
        }
    }
}

class WebSocketRemoteConsoleHandler implements MessageComponentInterface {
    protected $clients;
    private $worker;

    public function __construct() {
        $this->clients = new \SplObjectStorage;

        $this->worker = new WorkerThread($this);
        $this->worker->start();
    }

    public function onOpen(ConnectionInterface $conn) {
        $this->clients->attach($conn);
        $this->sendMessageToAllClients($this->worker->msgHistory, true); // Function displays "Connection count: 1"
    }

    public function onClose(ConnectionInterface $conn) {
        $this->clients->detach($conn);
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        $conn->close();
    }

    public function sendMessageToAllClients($data, $sendMsgHistory) {
        echo "Connection count: " . count($this->clients) . PHP_EOL;
        foreach($this->clients as $client) {
            $client->send(json_encode(array(
                "Messages" => $data,
                "IsComplete" => $sendMsgHistory
            )));
        }
    }
}

$server = IoServer::factory(
    new HttpServer(new WsServer(new WebSocketRemoteConsoleHandler())),
    8080
);
$server->run();
?>

当我从类内部调用方法sendMessageToAllClients()时，它显示Connection count: 1。当我从websocket类的同一实例中的线程调用函数时，它显示Connection count: 0。

我期望两个函数调用都应显示已连接1个客户端（Connection count: 1）。

（我已经启动了webocket，并使用javascript连接了它）
