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
<?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();
?>
