Example of using swoole to expand php websocket

The goal of the WebSocket specification is to implement bidirectional communication with the server in the browser. Two-way communication can expand the application types on the browser. If you want to use PHP to write websocket applications, swoole_framework must be the best choice. For more information, see

The Code is as follows:

<? Php

Define ('debug', 'on ');

Define ("WEBPATH", str_replace ("", "/", _ DIR __));

Require _ DIR _. '/../libs/lib_config.php ';

 

Class WebSocket extends SwooleNetworkProtocolWebSocket

{

/**

* Notify everyone when going offline

*/

Function onClose ($ serv, $ client_id, $ from_id)

{

// Send the offline message to everyone

// $ This-> log ("onOffline:". $ client_id );

// $ This-> broadcast ($ client_id, "onOffline:". $ client_id );

Parent: onClose ($ serv, $ client_id, $ from_id );

}

 

/**

* When a message is received

* @ See WSProtocol: onMessage ()

*/

Function onMessage ($ client_id, $ ws)

{

$ This-> log ("onMessage:". $ client_id. '='. $ ws ['message']);

$ This-> send ($ client_id, "Server:". $ ws ['message']);

// $ This-> broadcast ($ client_id, $ ws ['message']);

}

 

Function broadcast ($ client_id, $ msg)

{

Foreach ($ this-> connections as $ clid => $ info)

{

If ($ client_id! = $ Clid)

{

$ This-> send ($ clid, $ msg );

}

}

}

}

 

 

$ Alibaba Vr = new WebSocket ();

$ Export VR-> loadSetting (_ DIR _. "/swoole. ini"); // load the configuration file

$ Export VR-> setLogger (new SwooleLogEchoLog (true); // Logger

 

$ Server = new SwooleNetworkServer ('0. 0.0.0.0 ', 9503 );

$ Server-> setProtocol ($ community vr );

// $ Server-> daemonize (); // serves as the daemonize Process

$ Server-> run (array ('worker _ num' => 4 ));
