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.

Testing and troubleshooting the migration

In an ideal world, the migration troubleshooting will take place on the staging server, or simulated virtual environment, well before the actual move to production. However, as the seasoned developer well knows, we need to hope for the best, but prepare for the worst! In this section, we cover additional aspects of testing and troubleshooting that can be easily overlooked.

For the purposes of this section, you can exit the temporary shell if you were following the Debian/Ubuntu or the Red Hat/CentOS/Fedora installation process. Return to the Docker container used for this course and open a command shell into the PHP 8 container. Please refer to the Technical requirements section of Chapter 1, Introducing New PHP 8 OOP Features, for more information on how to do this if you are unsure.

Testing and troubleshooting tools

There are too many fine testing and troubleshooting tools available to document here, so we focus on a few open source...
