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 received an overview of major changes in error handling in PHP 8. You were also given examples of situations where error conditions might arise, and now have an idea of how to properly manage errors in PHP 8. You now have a solid path toward refactoring code that under PHP 8 now produces errors. If your code could potentially lead to any of the conditions described where former Warnings are now Errors, you risk having your code break.

In a like manner, although the second set of error conditions described only produced Notices in the past, these same conditions now cause a Warning. The new set of Warnings gives you a chance to adjust faulty code and prevent having your application devolve into a seriously unstable condition.

Finally, you learned how use of the @ operator is strongly discouraged. In PHP 8, this syntax will no longer mask fatal errors. In the next chapter, you will learn how to create C-language structures and make direct calls to...
