关于php的socket,该如何解决

关于php的socket
最近在学php的socket，想通过一个功能的实现检验我对socket的理解：
1、client端发送数据到服务器端
2、server端接收client发送过来的数据，并会送一个响应给client端
3、client端显示server端发过来的响应信息

以下是代码

server.php:
// Set up our socket
$commonProtocol = getprotobyname("tcp");
$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);
socket_bind($socket, 'localhost', 1234);
socket_listen($socket);
// Initialize the buffer
$buffer = "NO DATA";
while(true) {
// Accept any connections coming in on this socket
$connection = socket_accept($socket);
printf("Socket connected\r\n");
// Check to see if there is anything in the buffer
$buffer=socket_read($connection, 2048, PHP_NORMAL_READ);
echo "recived from client ".$buffer;
$ResponseToClient=$buffer." is handled by server!\n";
socket_write($connection, $ResponseToClient);
echo "response to client!\n ";
}
?>

client.php:
// Create the socket and connect
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$connection = socket_connect($socket,'localhost', 65500);
$i=0;
$s=0;
while(true)
{
echo "sending data".$i++."\n";
$SendDataToServer=socket_write($socket, "server".$s++);
$ResponseFromServer=socket_read($socket, 2048, PHP_NORMAL_READ);
echo "received".$ResponseFromServer."from server \n";
}
?>

问题是：client端只显示sending data0
而server端只显示Socket connected
其他什么也不显示，没有达到我预想的client不断发送数据，server端不断处理数据并返回给client的目的，请高手指教下，万分感谢 socket PHP

------解决方案--------------------
没有需求干嘛弄这个？
不过可以给你个早年写的测试例
服务端

// Server

// 设置错误处理

error_reporting (E_ALL);

// 设置运行时间

set_time_limit (0);

// 起用缓冲

ob_implicit_flush ();

$ip = "127.0.0.1";        // IP地址

$port = 1000;             // 端口号



$socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP);       // 创建一个SOCKET

if ($socket)

    echo "socket_create() successed!\n";

else

    echo "socket_create() failed:".socket_strerror ($socket)."\n";



$bind = socket_bind ($socket, $ip, $port);              // 绑定一个SOCKET

if ($bind)

    echo "socket_bind() successed!\n";

else

    echo "socket_bind() failed:".socket_strerror ($bind)."\n";



$listen = socket_listen ($socket);                 // 间听SOCKET

if ($listen)
