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

哪位大侠回复下啊

不是很清楚，为什么两边的端口不一样啊？

楼上+1
另：就算你的程序顺利执行，也是个死循环

看来大都没怎么么搞过socket,失望

我是觉得php在socket方面不靠谱啊。。。

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

<?php// 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$socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP);       // 创建一个SOCKETif ($socket)    echo "socket_create() successed!\n";else    echo "socket_create() failed:".socket_strerror ($socket)."\n";$bind = socket_bind ($socket, $ip, $port);              // 绑定一个SOCKETif ($bind)    echo "socket_bind() successed!\n";else    echo "socket_bind() failed:".socket_strerror ($bind)."\n";$listen = socket_listen ($socket);                 // 间听SOCKETif ($listen)    echo "socket_listen() successed!\n";else    echo "socket_listen() failed:".socket_strerror ($listen)."\n";while (true){    $msg = socket_accept ($socket);               // 接受一个SOCKET    if (!$msg)    {        echo "socket_accept() failed:".socket_strerror ($msg)."\n";        break;    }    $welcome = "服务端收到:Welcome to PHP Server!\n";    socket_write ($msg, $welcome, strlen ($welcome));    while (true)    {        $command = strtoupper (trim (socket_read ($msg, 1024)));        if (!$command)            break;        switch ($command)        {            case "HELLO":                $writer = "Hello Everybody!";                break;            case "QUIT":                $writer = "Bye-Bye";                break;            case "HELP":                $writer = "HELLO\tQUIT\tHELP";                break;            default:                $writer = "Error Command!";        }        socket_write ($msg, $writer, strlen ($writer));        if ($command == "QUIT")            break;    }    socket_close ($msg);    if ($command == "QUIT")        break;}socket_close ($socket);                   // 关闭SOCKET

客户端

<?php// Client // 设置错误处理error_reporting (E_ALL);// 设置处理时间set_time_limit (0);$ip = "127.0.0.1";       // IP 地址$port = 1000;            // 端口号$socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP);   // 创建一个SOCKETif ($socket)    echo "socket_create() 成功!<br>\n";else    echo "socket_create() 失败:".socket_strerror ($socket)."<br>\n";$conn = socket_connect ($socket, $ip, $port);       // 建立SOCKET的连接if ($conn)    echo "成功连接到[".$ip.":".$port."]<br>\n";else    echo "socket_connect() 失败:".socket_strerror ($conn)."<br>\n";echo socket_read ($socket, 1024)."<br>";$stdin = fopen ('php://stdin', 'r');$ar = array("HELLO","HELP","test","QUIT");$i = 0;while (true){//    $command = trim (fgets ($stdin, 1024));//    socket_write ($socket, $command, strlen ($command));echo "发送 $ar[$i]<br>";    socket_write ($socket, $ar[$i], strlen($ar[$i]));$i++;    $msg = trim (socket_read ($socket, 1024));    echo "收到:$msg<br>\n";    if ($msg == "Bye-Bye")        break;}fclose ($stdin);socket_close ($socket);

正常的话应该显示：
socket_create() 成功!
成功连接到[127.0.0.1:1000]
服务端收到:Welcome to PHP Server!
发送 HELLO
收到:Hello Everybody!
发送 HELP
收到:HELLO QUIT HELP
发送 test
收到:Error Command!
发送 QUIT
收到:Bye-Bye

是死循环
