Example – using Net_Server

Creating a simple daemon

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
  *
  * @access  public
  * @param  integer $clientId
  * @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();
?>
