Question

我正在使用php和mysql建立一个小网站。该网站还包括一个聊天应用程序，我现在使用Ratchet和php实现了一个模块。问题是我无法将聊天消息存储在一个MySql数据库。我也是Ratchet的初学者，按照这里的教程https://www.youtube.com/watch?v=RYpSG5d5IPk实现了聊天模块。谢谢提前:)我在这里发布聊天模块的代码：

的index.html

<html>


    <head>

        <meta charset="utf-8">
        <title>React Chat</title>
        <link rel="stylesheet" href="style.css">

    </head>

    <body>

        <div class = "container"> 

            <div class = "chat" id = "chatwindow"></div>

            <div class = "form">

                <textarea name = "message" id = "messagebox" placeholder = "Message :"></textarea>

            </div>
        </div>

        <script src = "js/app.js"></script>

    </body>



</html>

app.js

var chat = document.getElementById("chatwindow");
var msg = document.getElementById("messagebox");

var socket = new WebSocket("ws://127.0.0.1:2000");

var open = false;

function addMessage(msg){
    chat.innerHTML += "<p>" + msg + "</p>";
}

msg.addEventListener("keypress",function(evt){
    if (evt.keyCode != 13)
        return;

    evt.preventDefault();

    if (msg.value == "" || !open)
        return;

    socket.send(JSON.stringify({
        msg: msg.value
    }));

    addMessage(msg.value);

    msg.value = "";
});

socket.onopen = function(){

    open = true;

    addMessage("Connected");

};

socket.onmessage = function(evt){

    var data = JSON.parse(evt.data);
    addMessage(data.msg);

};

socket.onclose = function(){

    open = false;

    addMessage("Disconnected");

};

Chat.php

<?php

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class Chat implements MessageComponentInterface
{
    protected $clients;

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

    public function onOpen(ConnectionInterface $conn)
    {
        $this->clients->attach($conn);
    }

    public function onMessage(ConnectionInterface $conn,$msg)
    {
        foreach($this->clients as $client)
        {
            if ($client !== $conn)
            {
                $client->send($msg);
                $co = new mysqli("localhost", "root", "adil","test");

                // Check connection
                if ($co->connect_error) {
                    die("Connection failed: " . $co->connect_error);
                } 

                else {
                    $query = "insert into message('$msg')";
                    $co->query($query);
                }
            }
        }
    }

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

    public function onError(ConnectionInterface $conn,\Exception $e)
    {
        echo "The following error occured " . $e->getMessage();
        $conn->close();
    }

}

server.php

<?php

require __DIR__ . '/../vendor/autoload.php';

use Ratchet\Server\IoServer;
use Ratchet\http\HttpServer;
use Ratchet\WebSocket\WsServer;

$server = IoServer::factory(new HttpServer(new WsServer(new Chat)),2000);

$server->run();
