The following example shows, how easy it is to build a forking server that receives data and sends it back to the user.

Creating a simple talkback daemon

#!/usr/local/bin/php
<?php
    
// server base class
    
require_once 'Net/Server.php';
    
    
// base class for the handler
    
require_once 'Net/Server/Handler.php';

/**
 * simple example that implements a talkback.
 *
 * Normally this should be a bit more code and in a separate file
 */
class Net_Server_Handler_Talkback extends Net_Server_Handler
{
   
/**
    * If the user sends data, send it back to him

    * @param    string  $data
    */
    
function    onReceiveData$clientId 0$data "" )
    {
        
$this->_server->sendData$clientId"You said: $data);
    }
}
    
    
// create a server that forks new processes
    
$server  = &Net_Server::create('fork''localhost'9090);
    
    
$handler = &new Net_Server_Handler_Talkback;
    
    
// hand over the object that handles server events
    
$server->setCallbackObject($handler);
    
    
// start the server
    
$server->start();
