针对内容比较长出错，修改后的解码函数 和 加码函数 原文请看上一篇 http://yixun.yxsss.com/yw3104.html

function uncode($str,$key){

        $mask = array();

            $s = 12;

            $n=0;

        }else if($this->slen[$key] > 0){

            $n++;

        }

        $dlen=strlen($data);

        if($len > 255 && $len > $dlen+intval($this->sjen[$key])){

            $this->ar[$key]=$mask;

            $this->slen[$key]=$len;

            $this->sjen[$key]=$dlen+intval($this->sjen[$key]);

        }

    }

    function code($msg){

        $frame = array();

        $frame[0] = '81';

        $len = strlen($msg);

        if($len < 126){

            $frame[1] = $len<16?'0'.dechex($len):dechex($len);

        }else if($len < 65025){

            $s=dechex($len);

            $frame[1]='7e'.str_repeat('0',4-strlen($s)).$s;

        $frame[2] = $this->ord_hex($msg);

        $data = implode('',$frame);

        return pack("H*", $data);

    }

其中主函数run 里面的接收修改为

do{

    $l=socket_recv($sock,$buf,1000,0);

    $len+=$l;

    $buffer.=$buf;

}while($l==1000);

服务器端代码：

var fs = require('fs')

    , http = require('http')

    , socketio = require('socket.io');

var server = http.createServer(function(req, res) {

    res.writeHead(200, { 'Content-type': 'text/html'});

    res.end(fs.readFileSync(__dirname + '/index.html'));

}).listen(8080, function() {

    console.log('Listening at: http://localhost:8080');

});

var ids=[];

var io=socketio.listen(server);

io.on('connection', function (socket) {

    ids.push(socket.id);

    socket.on('key', function (msg) {

        console.log('Message Received: ', msg);

        console.log('sockid：'+socket.id);

        console.log(ids);

        io.sockets.socket(ids[0]).emit('key',msg);//向指定的用户发信息

                //socket.broadcast.emit('key', msg); //公告

        //socket.emit('key', msg); //发给自己

    });

    socket.on('disconnect',function(){

        console.log('关闭'+socket.id);

    });

});

最近弄html5最新功能WebSocket 网上找了很多资料 都是相互抄袭 而且用不了，经过2天的折腾 终于好了，不过还有昵称是中文名的时候会自动断了的问题 估计是转码的问题。
