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.

Chapter 12: Creating PHP 8 Applications Using Asynchronous Programming

In recent years, an exciting new technology has taken the PHP: Hypertext Preprocessor (PHP) community by storm: asynchronous programming, also known as PHP async. The asynchronous programming model addresses an issue present in any application code written using the traditional synchronous mode of programming: your application is forced to wait for certain tasks to complete before providing results. The central processing unit (CPU) (or CPUs) of the server upon which your application is running sits idle while mundane input/output (I/O) tasks are performed. PHP async allows your application to take full advantage of hardware resources by suspending blocking I/O tasks until later. The net effect is a massive increase in performance, as well as the ability to handle a geometrically larger number of user requests.

After reading through this chapter and carefully studying the examples, you will be able to develop...
