Mastering Swoole PHP: Build High Performance Concurrent System with Async and Coroutines

Description

Build your high performance large scale concurrent system in a more flexible and efficient way than ever before with this first & only Swoole book, with PHP 8 ready. Introduction Introducing a new execution model of PHP applications, how Open Swoole works and the pitfalls of new developers coming into the Open Swoole world. This book is also about the general concepts behind building a high concurrency and high-performance web system and how these concepts are implemented in Open Swoole and how advanced PHP works. This book provides just enough Linux OS kernel knowledges with code samples helping you understand how async I/O, concurrency and coroutine works. When start learning or using a new framework, people always carry some assumption coming from the previous experience. Some of these experiences are helpful to understand the new system, but some of these experiences may lead to the misunderstanding of the new system. This book introduces the pitfalls to avoid if you are an experienced PHP developer. This book is for the developers who have already know the basics about how a web system works such as PHP web application or application in the other programming languages such as Node.js, Golang or Java. After reading this book, you should be able to build a high concurrent Swoole PHP system with confidence.
