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!

Implementing the chat application

After this short introduction in the development with WebSockets, let us now begin implementing the actual chat application. The chat application will consist of the server-side application built in PHP with Ratchet, and an HTML and JavaScript-based client that will run in the user's browser.

Bootstrapping the project server-side

As mentioned in the previous section, applications based on ReactPHP will achieve the best performance when used with an event-loop extension such as libevent or ev. Unfortunately, the libevent extension is not compatible with PHP 7, yet. Luckily, ReactPHP also works with the ev extension, whose latest version already supports PHP 7. Just like in the previous chapter, we'll be working with Docker in order to have a clean software stack to work on. Start by creating a Dockerfile for your application container:

FROM php:7 
RUN pecl install ev-beta && \ 
    docker-php-ext-enable ev 
WORKDIR /opt/app 
CMD ["/usr/local/bin/php...
