PHP 8 Programming Tips, Tricks and Best Practices

By: Doug Bierer

Overview of this book

Thanks to its ease of use, PHP is a highly popular programming language used on over 78% of all web servers connected to the Internet. PHP 8 Programming Tips, Tricks, and Best Practices will help you to get up-to-speed with PHP 8 quickly. The book is intended for any PHP developer who wants to become familiar with the cool new features available in PHP 8, and covers areas where developers might experience backward compatibility issues with their existing code after a PHP 8 update. The book thoroughly explores best practices, and highlights ways in which PHP 8 enforces these practices in a much more rigorous fashion than its earlier versions. You'll start by exploring new PHP 8 features in the area of object-oriented programming (OOP), followed by enhancements at the procedural level. You'll then learn about potential backward compatible breaks and discover best practices for improving performance. The last chapter of the book gives you insights into PHP async, a revolutionary new way of programming, by providing detailed coverage and examples of asynchronous programming using the Swoole extension and Fibers. By the end of this PHP book, you'll not only have mastered the new features, but you'll also know exactly what to watch out for when migrating older PHP applications to PHP 8.

Learning about PHP 8.1 fibers

A Request for Comments (RFC) was published in March 2021 by Aaron Piotrowski and Niklas Keller, both PHP core team developers, outlining the case for including support for fibers in the PHP language core. The RFC was ratified at the end of the month and has now been implemented in the upcoming 8.1 version of PHP.

The fiber implementation is low-level, meaning that it is mainly designed to be used as part of a PHP async framework such as ReactPHP or Amp, or an extension such as the Swoole extension. Because this will, as of PHP 8.1 and beyond, be a core part of the language, developers will not have to worry so much about which extensions are loaded. Also, this greatly enhances PHP async frameworks as they now have low-level support, directly in the language core, greatly improving performance. Let's now have a look at the Fiber class itself.

Discovering the Fiber class

The PHP 8.1 Fiber class offers a bare-bones implementation upon which...
