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!

Tip

This section is meant to give you an overview on how to deploy a Ratchet application in a production environment. For the remaining sections of this chapter, we will continue using the Docker-based development setup (without load balancing and fancy process managers) for the sake of simplicity.

This will open an entire set of new problems to solve. One of them is scalability: by default, PHP runs single-threaded, so even when using the asynchronous event loop offered by libev, your application will never scale beyond a single CPU. While you could consider using the pthreads extension to enable threading in PHP (and to enter a whole new world of pain), it is usually easier to...
