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 9: Mastering PHP 8 Best Practices

In this chapter, you will be introduced to the best practices that are currently enforced in PHP 8. We will cover several significant method signature changes and how their new usage continues the general PHP trend of helping you produce better code. We will also have a look at how private methods, interfaces, traits, and anonymous class usage has changed. Finally, we will discuss important changes in how namespaces are parsed.

Mastering the best practices that will be covered in this chapter will not only move you toward writing better code, but how to avoid the potential code breaks that might arise if you fail to grasp these new practices. In addition, the techniques discussed in this chapter will help you write code that's more efficient than was possible in the past.

In this chapter, we will cover the following topics:

  • Discovering method signature changes
  • Dealing with private methods
  • Working with interfaces and...
