标题: PHP与C++通信遇到一个问题！
php端的代码如下：

1. 
   
2. <?php
   
3.     $sh = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
   
4.     if (socket_connect($sh, '127.0.0.1', 27015)) {
   
5.         echo "Socket connected correctly<br>";
   
6.     }
   
7.     $buf = 'Test Message';
   
8.     $len = strlen($buf);
   
9.     if (socket_send($sh, $buf, $len, 0x1) !== false) {
   
10.         echo "Message sent correctly";
    
11.     }
    
12.     socket_close($sh);
    
13. ?>

C++的服务端：

1. 
   
2. #include <windows.h>
   
3. #include <iostream.h>
   
4. #include <Winsock2.h>
   
5. 
   
6. #define NO_FLAGS_SET 0
   
7. 
   
8. #define PORT (u_short) 27015
   
9. #define MAXBUFLEN 1024
   
10. 
    
11. INT main(VOID)

50.     cerr << "ERROR: listen unsuccessful" << endl;
    
51. 
    
52.   /* accept the connection request when one
    
53.      is received */
    
54.   clientSocket=accept(serverSocket, (LPSOCKADDR) &clientSockAddr, &addrLen);
    
55. 
    
56.   cout << "Got the connection..." << endl;
    
57. 
    
58.   while(1)

60.     numrcv=recv(clientSocket, buffer, MAXBUFLEN, NO_FLAGS_SET);
    
61.     if ((numrcv == 0) || (numrcv == SOCKET_ERROR))
    
62.     {
    
63.       cout << "Connection terminated." << endl;
    
64.       status=closesocket(clientSocket);

69.         cerr << "ERROR: WSACleanup unsuccessful" << endl;
    
70.       return(1);
    
71.     }
    
72.     cout << buffer << endl;
    
73.   } /* while */
    
74. }

现在遇到的问题是：PHP送出的字符串“Test Message”，服务器端显示的为“Test Messagq”，最后一位出错了。我的编译环境为MinGW。请大虾们指点。

可以参考下这个示例, "CGI 与后台程序用 socket 进行消息通信"
