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 about deprecated and removed PHP functionality. The first section in this chapter dealt with core functionality that has been removed. The rationale for the change was explained, and you learned that the main reason for removing the functionality described in this chapter is not only to move you toward code that follows best practices but to have you use PHP 8 functionality that is faster and more efficient.

In the next section, you learned about deprecated functionality. The key theme in this section was to highlight how the deprecated functions, classes, and methods lead to bad practices and bug-ridden code. You also were given guidance on functionality that has been either removed or deprecated in a number of key PHP 8 extensions.

You learned how to locate and rewrite code that has been deprecated, and how to develop workarounds for functionality that has been removed. Another skill you learned in this chapter included how to refactor code...
