README

Protocol WebSocket (standard RFC 6455) is designed to solve any problems and the removal of restrictions communication between browser and server.It allows you to transfer any data to any domain, safe and almost without unnecessary network traffic.

The main advantages of this module is that you can create a variety of applications based on Zend Framework 2, where it is necessary to implement persistent connections. Thanks to one interface, you can create a variety of applications and run them on the same server. You can organize a chat, monitor live site visit, you can create real-time statistics and save it to DB (MySQL, Mongo..etc), you can organize the postal service in the likeness of Google. Yes, anything!

vendor\ZF2\library\Zend\Mvc\View\Console\RouteNotFoundStrategy.php 381 and replace line by

<?php
$result .= isset($row[0]) ? $row[0] . "\n" : '';
?>

It might be fixed until not fix in the next update. You're always can ask me for this module if you have write me issue

Installation and Running Server :

1. First update your dependencies through composer. Then run to update dependency and update autoloader

php composer.phar require stanislav-web/zf2-websocket-server-factory
php composer.phar install -o

1. That needs to be done is adding it to your application's list of active modules. Add module "WebSockets" in your application.config.php

2. Perform module configuration file module.config.php

3. Go to your shell command-line interface and type (running server as background): php -q index.php websocket open <app> (app like as your client application)

4. Setup your Client-side script's to communicating with the server .. ws://host:port/websocket/open/

How can i do the Application ?

New application you can do according to the rules interface

src\WebSockets\Aware\ApplicationInterface.php

As an example, you can see the implementation "Chat"

src\WebSockets\Application\Chat.php

then call server from your cli controller

<?php

	    // get factory container
        $factory = new ApplicationFactory($this->getServiceLocator());

        // applications from response <app>
	    // get it @see /src/WebSockets/Application/Chat.php etc..

	    $client	= $request->getParam('app');

	    $app	= $factory->dispatch(ucfirst($client)); 
	    
	    // bind events from application 
	    // ! must be implements of your every new Application
	    $app->bind('open', 'onOpen');
	    $app->bind('message', 'onMessage');
	    $app->bind('close', 'onClose');

	    // running server
	    $app->run();
?>

In order to start using the module clone the repo in your vendor directory or add it as a submodule if you're already using git for your project: git clone https://github.com/stanislav-web/ZF2-PHP-WebSocket-Server-Factory.git vendor/WebSockets or git submodule add git clone https://github.com/stanislav-web/ZF2-PHP-WebSocket-Server-Factory.git vendor/WebSockets

The module will also be available as a Composer package soon.
