Async PHP: The Complete Guide

PHP has traditionally been associated with synchronous script execution, but the modern realities of high-load web applications require a different approach. The book "Async PHP: The Complete Guide" is a practical guide that covers all aspects of non-blocking programming in PHP: from basic event loop concepts to building industrial microservices based on ReactPHP and Amp.

What this book is about

You will learn how asynchrony works at the operating system level, get acquainted with the mechanisms of Fibers (introduced in PHP 8.1) and coroutines. The author explains step by step:

• Why traditional PHP blocks I/O and how to fix it
• The event loop architecture in ReactPHP and Amp libraries
• Creating parallel HTTP clients and WebSocket servers
• Managing data streams via Streams and Promises
• Integrating asynchronous components with popular frameworks (Laravel, Symfony)
• Errors and debugging in an asynchronous environment

Who it is for

The book will be useful for:

• PHP developers looking to improve the performance of their applications
• DevOps engineers working with high-load systems
• Architects designing event-driven architectures
• Team leads implementing modern practices in their teams

What you will get

After reading, you will be able to:

• Write non-blocking code without "callback hell"
• Create real-time applications (chats, notifications, monitoring)
• Optimize processing of large volumes of data
• Deploy asynchronous workers for background tasks
• Apply reactive programming patterns in production

All code examples are up-to-date for PHP 8.1+ and come with practical exercises. The book contains 15 chapters, 200+ pages, and 50+ ready-to-use snippets. Perfect for both self-study and corporate training.

Dive into the world of async PHP — and your applications will stop waiting!
