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 how to write better code using the new PHP 8 data types: mixed and union types. You also learned about how using named arguments can not only improve the readability of your code but can also help prevent accidental misuse of class methods and PHP functions, as well as providing a great way to skip over default arguments.

This chapter also taught you how the new Attribute class can be used as an eventual replacement for PHP DocBlocks, serving to improve the overall performance of your code while providing a solid means of documenting classes, methods, and functions.

In addition, we looked at how PHP 8 can greatly reduce the amount of code needed by earlier PHP versions by taking advantage of constructor argument promotion and typed properties.

In the next chapter, you will learn about new PHP 8 features at the functional and procedural level.
