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.

In this chapter, you learned not only how the new JIT compiler works, but you gained an understanding of the traditional PHP interpret-compile-execute cycle. Using PHP 8 and enabling the JIT compiler has the potential to speed up your PHP application anywhere from three times faster and up.

In the next section, you learned what a stable sort is, and how PHP 8 implements this vital technology. By mastering the stable sort, your code will produce data in a rational manner, resulting in greater customer satisfaction.

The section following introduced you to a technique that can vastly improve performance and reduce memory consumption by taking advantage of the SplFixedArray class. After that, you learned about PHP 8 support for weak references as well as the new WeakMap class. Using the techniques covered in this chapter will cause your applications to execute much quicker, run more efficiently, and use less memory.

In the next chapter, you'll learn how to perform...
