C#写的客户端连接 php的服务器端的小例子

php的server 端

<?php

// server.php
set_time_limit( 0 );
ob_implicit_flush();
$socket = socket_create( AF_INET, SOCK_STREAM, SOL_TCP );
socket_bind( $socket, '127.0.0.1', 8880 );
socket_listen($socket);
$acpt=socket_accept($socket);
echo "> Acpt!\n";
while ( $acpt ) {
    echo "> ";
    $words= trim(fgets(STDIN));
    if(strlen($words) === 0) $words = "\n";
    socket_write($acpt,$words);
    $hear=socket_read($acpt,1024);
    echo "client>" . $hear . "\n" ;
    if("bye"==$hear){
        socket_shutdown($acpt);
        break;
    }
    usleep( 1000 );
}
socket_close($socket);
echo "> bye bye\n";
?>

以交互式方法运行：

php -a server.php

C#写的客户端

public class Client
    {
        private static byte[] result = new byte[1024];
        public string serverIp = "127.0.0.1";
        public int severPort = 8880;

        public Client(string serverIp, int serverPort)
        {
            this.serverIp = serverIp;
            this.severPort = serverPort;
        }

        public void start()
        {
            //设定服务器IP地址
            IPAddress ip = IPAddress.Parse(serverIp);
            Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            try {
                clientSocket.Connect(new IPEndPoint(ip, severPort));
                Console.WriteLine("连接服务器成功");
            } catch {
                Console.WriteLine("连接服务器失败");
                return;
            }

            int receiveLength;
            while (clientSocket.Connected) {

                receiveLength = clientSocket.Receive(result);
                string sv_word = Encoding.ASCII.GetString(result, 0, receiveLength);
                Console.WriteLine("Sever> {0}", sv_word);

                if (sv_word.Trim() == "bye") break;

                Console.Write("> ");
                string words = Console.ReadLine();
                if (string.IsNullOrEmpty(words)) words = "\n";
                clientSocket.Send(Encoding.ASCII.GetBytes(words));

                if (words.Trim() == "bye") break;


            }

           if(clientSocket.Connected) clientSocket.Close();
           Console.WriteLine("> bye bye");

        }
    }

加入引入

using System.Net;
using System.Net.Sockets;
using System.Threading;

在某处调用

new Client("127.0.0.1", 8880).start();

OK
交互吧
