Overview of this book

When it comes to modern web development, performance is everything. The latest version of PHP has been improvised and updated to make it easier to build for performance, improved engine execution, better memory usage, and a new and extended set of tools. If you’re a web developer, what’s not to love? This guide will show you how to make full use of PHP 7 with a range of practical projects that will not only teach you the principles, but also show you how to put them into practice. It will push and extend your skills, helping you to become a more confident and fluent PHP developer. You’ll find out how to build a social newsletter service, a simple blog with a search capability using Elasticsearch, as well as a chat application. We’ll also show you how to create a RESTful web service, a database class to manage a shopping cart on an e-commerce site and how to build an asynchronous microservice architecture. With further guidance on using reactive extensions in PHP, we’re sure that you’ll find everything you need to take full advantage of PHP 7. So dive in now!

Bridging Ratchet and PSR-7 applications


Sooner or later, your chat application will also need to respond to regular HTTP requests (for example, this will become necessary as soon as you want to add an authentication layer with a login form and authentication processing).

As explained in the previous section, a common setup for WebSocket applications in PHP is to have a Ratchet application handle all WebSocket connections, and to direct all regular HTTP requests to a regular PHP-FPM setup. However, as a Ratchet application in fact also ships its own HTTP server, you can also respond to regular HTTP requests directly from your Ratchet application.

Just as you have used the Ratchet\MessageComponentInterface to implement WebSocket applications, you can use the Ratchet\HttpServerInterface to implement a regular HTTP server. As an example, consider the following class:

namespace Packt\Chp6\Http; 
 
use Guzzle\Http\Message\RequestInterface; 
use Ratchet\ConnectionInterface; 
use Ratchet\HttpServerInterface...
