Learning Event-Driven PHP With ReactPHP

About the Book

A lot has changed since PHP was used only for rendering web-pages. Now PHP is something more than a simple script, which is used to render a web page in a request-response cycle. The event-driven architecture and asynchronous I/O processing of any number of streams in real time allow you to build a whole new category of applications. This book covers everything you should know about creating asynchronous applications in ReactPHP. We start with the basics, such as an event loop, timers, and streams. And then gradually we will move to more advanced topics and real applications examples. ReactPHP has a great set of components and a real ecosystem of third-party libraries.

The book covers all ReactPHP core components with theory and code examples to give you a solid basis to build your own asynchronous application for your own use-case. If you have always written PHP applications in a traditional synchronous way, it will be an eye-opening book for you. 

Also, I'm going to keep this book up-to-date with ReactPHP releases. That means that when a new feature comes out or something becomes deprecated or even removed, the book will also reflect these changes and will be republished and you will receive these updates for free!
