PHP套接字服务器中的对等连接重置

我正在尝试为messenger编写一个PHP套接字服务器。这是我的PHP代码：

if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) {
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
}

if (socket_bind($sock, $address, $port) === false) {
    echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
}

if (socket_listen($sock, 100) === false) {
    echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
}

//clients array
$clients = array();

do {
    $read = array();
    $read[] = $sock;

    $read = array_merge($read, $clients);

    // Set up a blocking call to socket_select
    if (@socket_select($read, $write = NULL, $except = NULL, $tv_sec = 100) < 1) {
        //    SocketServer::debug("Problem blocking socket_select?");
        continue;
    }

    // Handle new Connections
    if (in_array($sock, $read)) {

        if (($msgsock = socket_accept($sock)) === false) {
            echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
            break;
        }
        $clients[] = $msgsock;
        $key = array_keys($clients, $msgsock);
        /* Enviar instrucciones. */
        $msg = "\nWelcome to the PHP Test Server. \n" .
            "Client key number: {$key[0]}\n" .
            "To quit, type 'quit'. To shut down the server type 'shutdown'.\n";
        socket_write($msgsock, $msg, strlen($msg));

    }

    // Handle Input
    foreach ($clients as $key => $client) { // for each client
        if (in_array($client, $read)) {
            if (false === ($buf = socket_read($client, 4096, PHP_NORMAL_READ))) {
                echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($client)) . "\n";
                break 2;
            }
            if (!$buf = trim($buf)) {
                continue;
            }
            if ($buf == 'quit') {
                unset($clients[$key]);
                socket_close($client);
                break;
            }
            if ($buf == 'shutdown') {
                socket_close($client);
                break 2;
            }
            $talkback = "Client {$key}: Said: '$buf'.\n";
            socket_write($client, $talkback, strlen($talkback));
            echo "$buf\n";
        }

    }
} while (true);

我必须做些什么来解决这个问题。

谢谢大家!

你的android代码在哪里？所以服务器正在尝试读取。但是客户端发送的是什么？在你的客户端代码中没有写东西。它不能测量客户端试图发送什么。你是什么意思？请再努力解释一下应该发生什么。您需要帮助，不是吗？例如：我运行这个php套接字服务器，当我通过终端（终端ip端口）连接时，它工作得非常好。当我试图通过Android连接未连接并显示错误时：

socket\u read（）失败：原因：对等方重置连接

。我写了《你好，世界》

InetAddress serverAddr;
try {
    serverAddr = InetAddress.getByName(dstAddress);
} catch (UnknownHostException e) {
    e.printStackTrace();
}
try {
    socket = new Socket(serverAddr, SERVERPORT);
    socket.setSendBufferSize(10000);
    commThread.setClientSocket(socket);

    cmThread = new Thread(commThread);
    connected = true;
} catch (Exception e) {
    connected = false;
}
