我试图用php制作简单的套接字应用程序。好的，原则是处理这些房间内的n个聊天室和多个功能，这些功能涉及通过套接字进行客户端到客户端的通信。所以这就是我到目前为止所做的：
客户端连接，与标头的握手通过ok
套接字脚本将客户端存储在数组中，处理新连接和断开连接，跟踪哪个客户端具有哪些房间（n：n）等
客户端我使用自己的语法如何控制套接字服务器，例如加入一个房间 - ＆gt; ＆＃34; delimiteraction：joindelimiterid：2delimiter＆＃34;，但问题在这里上升。握手后，我无法从套接字中获取任何人类可读的数据。我使用putty监视套接字脚本，它主要显示白条，其中数据也应该是每次数据似乎不同（相同的客户端消息但不同的套接字数据），但长度大多相同（不是非阻塞问题已经尝试阻止）
我尝试过解码，编码，二进制转换，尝试使用流和套接字，但似乎没有任何效果。
我是套接字的新手，但不是php。 这是客户端代码：
var delimiter = "maybeencodesomeofit";
var connection = new WebSocket('ws://myip:myport');
connection.onopen = function(e){//define handshake
alert("connection established");
var message = delimiter+"action:join"+delimiter+"userid:1"+"EOD_MARK";
connection.send("somegood10lobbyid:1somegood10body:"+message+"\r");
}
connection.onerror = function (error){
alert("connection errored");
console.log(error);
}
connection.onmessage = function(e){
alert("connection message");
}
connection.onclose = function(e){
alert("closed connection");
}
此处的服务器代码：
<?php
set_time_limit(0);
// create a streaming socket, of type TCP/IP
$sock = stream_socket_server("tcp://myip:myport", $errno, $errstr);
stream_set_blocking($sock,TRUE);

我找到了解决方案，您需要取消屏蔽客户端到服务器数据然后重新编码，unmask功能需要能够处理多个帧（nagle算法）。下面的代码将相应地取消屏蔽多个帧 这是代码：
function unmask($payload){
$decMessages = Array();
do { // This should be running until all frames are unmasked and added to
$decMessages Array
$length = ord($payload[1]) & 127;
if($length == 126) {
$payload_len = 8;
$masks = substr($payload, 4, 4);
$data = substr($payload, 8);
$len = (ord($payload[2]) << 8) + ord($payload[3]);
}elseif($length == 127) {
$payload_len = 14;
$masks = substr($payload, 10, 4);
$data = substr($payload, 14);
$len = (ord($payload[2]) << 56) + (ord($payload[3]) << 48) +
(ord($payload[4]) << 40) + (ord($payload[5]) << 32) +
(ord($payload[6]) << 24) +(ord($payload[7]) << 16) +
(ord($payload[8]) << 8) + ord($payload[9]);
}else{
$payload_len = 6;
$masks = substr($payload, 2, 4);
$data = substr($payload, 6);
$len = $length;
}
$text = '';
for ($i = 0; $i < $len; ++$i) {
$text .= $data[$i] ^ $masks[$i%4];
}
$decMessages[] = $text;
$payload = substr($payload, $payload_len+$len, strlen($payload));
}while (($len < strlen($data)) and $countert < 10);
return $decMessages;
}
function encode($message){
$length = strlen($message);
$bytesHeader = [];
$bytesHeader[0] = 129; // 0x1 text frame (FIN + opcode)
if ($length <= 125) {
$bytesHeader[1] = $length;
}else if($length >= 126 && $length <= 65535) {
$bytesHeader[1] = 126;
$bytesHeader[2] = ( $length >> 8 ) & 255;
$bytesHeader[3] = ( $length ) & 255;
}else{
$bytesHeader[1] = 127;
$bytesHeader[2] = ( $length >> 56 ) & 255;
$bytesHeader[3] = ( $length >> 48 ) & 255;
$bytesHeader[4] = ( $length >> 40 ) & 255;
$bytesHeader[5] = ( $length >> 32 ) & 255;
$bytesHeader[6] = ( $length >> 24 ) & 255;
$bytesHeader[7] = ( $length >> 16 ) & 255;
$bytesHeader[8] = ( $length >> 8 ) & 255;
$bytesHeader[9] = ( $length ) & 255;
}
$str = implode(array_map("chr", $bytesHeader)) . $message;
return $str;
}
