socket能监听到数据 但是发送不出去呢

Question

<?php
error_reporting(E_ALL);
set_time_limit(0);
//ob_implicit_flush();

$ip = 'xxx';
$port = 6666;
//创建端口
if( ($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) {
    echo "socket_create() failed :reason:" . socket_strerror(socket_last_error()) . "n";
}

//绑定
if (socket_bind($socket, $ip, $port) === false) {
    echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($socket)) . "n";
}

//监听
if (socket_listen($socket, 5) === false) {
    echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($socket)) . "n";
}

do {
    //得到一个链接
    if (($msgsocket = socket_accept($socket)) === false) {
        echo "socket_accepty() failed :reason:".socket_strerror(socket_last_error($socket)) . "n";
        break;
    }
    //welcome  发送到客户端
    $msg ="server send:welcome";
    socket_write($msgsocket, $msg, strlen($msg));
    echo 'read client messagen';
    $buf = socket_read($msgsocket, 8192);
    $talkback = "$bufn";
    echo $talkback;
    if (false === socket_write($msgsocket, $talkback, strlen($talkback))) {
        echo "socket_write() failed reason:" . socket_strerror(socket_last_error($socket)) ."n";
    } else {
        echo 'send success';
    }
    socket_close($msgsocket);
} while(true);
//关闭socket
socket_close($socket);

?>

{"msghead":{"msgid":26,"uid":12502559,"rid":"841049","transmode":1},"msgbody":{"srcuid":12502559,"dstuid":12502559,"rid":"841049","gid":"1024","giftname":"u6211u9519u4e86","count":"1","time":1413386346,"type":2,"nickname":"jinkang","wealth":"451350","credit":"355311","identity":"2","star":1,"date":"23:19"}}  能监听到数据 但是服务端发送的 怎么客户端接收不到呢

// 加一句这个试下
socket_set_block($msgsocket); 
if(socket_write($msgsocket, $talkback, strlen($talkback))){
....

为啥不用开源的socket框架呢？自己写 socket 
daemon容易挂
