PHP与C++通信遇到一个问题！

lbblscy

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：

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"
