使用PHP连接到棘轮Websocket服务器

我在后端运行Ratchet WebSocketServer,一切正常.

<?php

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

use Ratchet\WebSocket\WsServer;
use Ratchet\Http\HttpServer;

$wsServer = new WsServer(new Chat());
$wsServer->disableVersion(0);

$server = \Ratchet\Server\IoServer::factory(
    new HttpServer(
        $wsServer
    ),
    8080
);

$server->run();

但是我想使用简单的php脚本连接到websocket,以将消息发送到服务器.

$host = 'ws://localhost';  //where is the websocket server
$port = 8080;
$local = "http://example.com";  //url where this script run 
$data = "first message";  //data to be send

$head = "GET / HTTP/1.1"."\r\n".
    "Upgrade: WebSocket"."\r\n".
    "Connection: Upgrade"."\r\n".
    "Origin: $local"."\r\n".
    "Host: $host:$port"."\r\n".
    "Sec-WebSocket-Key: asdasdaas76da7sd6asd6as7d"."\r\n".
    "Content-Length: ".strlen($data)."\r\n"."\r\n";

//WebSocket handshake
$sock = fsockopen($host, $port);
fwrite($sock, $head ) or die('error:'.$errno.':'.$errstr);
$headers = fread($sock, 2000);

echo $headers;

fwrite($sock, $data) or die('error:'.$errno.':'.$errstr);
$wsdata = fread($sock, 2000);
fclose($sock);

但是我收到的错误是.

error:32744:Unable to find the socket transport "ws" - did you forget   to enable it when you configured PHP?

然后,当我更改主机并且不使用ws：//时,它说.

error:111:Connection refused

有谁知道如何将数据从纯PHP文件发送到正在运行的Ratchet WebSocket服务器？

解决方法:

我已经与Ratchet一起尝试了这个项目,它可以完美地用作PHP客户端：

https://github.com/Textalk/websocket-php

安装方式：
作曲家需要textalk / websocket 1.0.*

还有一个用法示例：

<?php

require('vendor/autoload.php');

use WebSocket\Client;

$client = new Client("ws://127.0.0.1:1234");
$client->send("Hello from PHP");

echo $client->receive() . "\n"; // Should output 'Hello from PHP'

我进行了测试,如果您使用wss：//(用于远程websocket),则该方法也可用于SSL.
