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.

Preface

PHP 8 represents the culmination of the PHP core development team's work to maximize efficiency in the core language. Your application code will immediately see a boost in speed as well as having a smaller memory footprint just by migrating to PHP 8. Further, in PHP 8, developers notice that a tremendous effort has gone into normalizing syntax and language usage. In short, programming in PHP 8 is a joy to developers who appreciate adherence to good coding practices.

However, this inevitably leads to the question: where does the PHP language go from here? PHP 8 provides the answer to this question as well, in the form of the Just-In-Time compiler and support for fibers. The latter forms the foundation of asynchronous programming and has been announced for PHP 8.1. PHP 8 gives you a glimpse of the future of the language, and that future is looking extremely bright!

If you put all this together, it becomes clear that understanding and mastering the new features and stricter coding practices implemented in PHP 8 is vital to those who wish to pursue a serious career as a PHP developer. This book is exactly the tool you need to get up and running with PHP 8 quickly. Not only do we cover new features, but we also show you how to avoid traps that could lead to code failure after a PHP 8 migration. In addition, we give you a glimpse into the future of PHP via thorough coverage of the JIT compiler and PHP asynchronous programming.
