求助：PHP+SOCKET 由于套接字没有连接并且没有提供地址，发送或接收数据的请求没有被接受。
本帖最后由 subendong 于 2011-06-03 16:39:41 编辑 由于之前连续发布了两篇帖子，无一有回，所以先向版主申请删除之前两篇类似的帖子，不然留着无用。就像垃圾一样。
然后希望大神，能根据我提供的代码，稍作修改，使得代码能够正确运行，谢谢！
具体如下：
Warning: socket_read(): unable to read from socket [0]: 由于套接字没有连接并且(当使用一个 sendto 调用发送数据报套接字时)没有提供地址，发送或接收数据的请求没有被接受。
我建了两个文件xx.php是在服务器端执行的文件。x.php是在客户端执行的文件。
xx.php
<?php
// 设置一些基本的变量
global $lat,$lnt;

// 创建一个Socket
$commonProtocol = getprotobyname("tcp");
$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);
//绑定Socket到端口
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
