Socket programming in PHP from localhot to live server - php

Question

I want to use socket programming in php, Here i want to send response from local machine to live sever (ex. www.example.com).
In example.com i want to catch the response.
I tried lot of ways which are available on internet, but nothing usable for me.
Suppose...I want to use this technique for chat application.
I'm able to send and receive response from local to local and xyz live server to xyz live server....
Now i want to access this from local to xyz OR abc to 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);
?>

Maybe workerman can help you.
It's a socket framework for php.
http://github.com/walkor/workerman
For example a simple chat server
File:Applications/SimpleChat/start.php
<?php
use Workerman\Worker;
$global_uid = 0;
$connections_array = array();
function handler_connection($connection)
{
global $connections_array, $global_uid;
$connection->uid = ++$global_uid;
$connections_array[$connection->uid] = $connection;
}
// send to all
function handle_message($connection, $data)
{
global $connections_array;
foreach($connections_array as $conn)
{
$conn->send("user[{$connection->uid}] said: $data");
}
}
// clear
function handle_close($connection)
{
global $connections_array;
unset($connections_array[$connection->uid]);
}
// Websockt
$text_worker = new Worker("Text://0.0.0.0:2347");
// one process
$text_worker->count = 1;
$text_worker->onConnect = 'handler_connection';
$text_worker->onMessage = 'handle_message';
$text_worker->onClose = 'handle_close';
Then you can use telnet command to test .
telnet 127.0.0.1 2347
