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
回复讨论(解决方案)
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
客户端 \n";else echo "socket_create() 失败:".socket_strerror ($socket)."
\n";$conn = socket_connect ($socket, $ip, $port); // 建立SOCKET的连接if ($conn) echo "成功连接到[".$ip.":".$port."]
\n";else echo "socket_connect() 失败:".socket_strerror ($conn)."
\n";echo socket_read ($socket, 1024)."
";$stdin = fopen ('php://stdin', 'r');$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]
"; socket_write ($socket, $ar[$i], strlen($ar[$i]));$i++; $msg = trim (socket_read ($socket, 1024)); echo "收到:$msg
\n"; if ($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
