从localhot到live服务器的PHP套接字编程

我想在php中使用套接字编程，在这里我想将响应从本地机器发送到实时服务器（例如www.example.com）。

在example.com中，我想捕捉响应。

我尝试了很多互联网上可用的方法，但对我来说都没有用。

假设。。。我想在聊天应用程序中使用这种技术。

我能够从本地到本地以及从xyz实时服务器到xyz实时服务发送和接收响应。。。。

现在我想从本地访问xyz或从abc访问xyz

//client.php
<form method="POST">
    <input type="text" name="message">
    <input type="submit">
</form>

<?php
if (isset($_POST['message']) && $_POST['message'] != ''){
/*
 * PHP Sockets - How to create a sockets server/client 
 */
//include the server.php script to start the server
//include_once('server.php');
$host    = "192.186.246.136";
$port    = 4096;
$message = $_POST['message'];
echo "Message To server :".$message;
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket'n");
// connect to server
$result = socket_connect($socket, $host, $port) or die("Could not connect to server'n");  
// send string to server
socket_write($socket, $message, strlen($message)) or die("Could not send data to server'n");
// get server response
$result = socket_read ($socket, 1024) or die("Could not read server response'n");
echo "Reply From Server  :".$result;
// close socket
socket_close($socket);
}
?>


  //Server.php
  <?php
// set ip and port
$host = "192.186.246.136";
$port = 4096;
// don't timeout!
set_time_limit(0);
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0);
// bind socket to port
$result = socket_bind($socket, $host, $port);
// start listening for connections
$result = socket_listen($socket, 3);
// accept incoming connections
// spawn another socket to handle communication
$spawn = socket_accept($socket) or die("Could not accept incoming connection'n");
// read client input
$input = socket_read($spawn, 1024) or die("Could not read input'n");
// clean up input string
$input = trim($input);
echo "Client Message : ".$input."<br />";
// reverse client input and send back
$output = strrev($input) ."<br />";
socket_write($spawn, $output, strlen ($output)) or die("Could not write output'n");
// close sockets
socket_close($spawn);
socket_close($socket);
