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.

Chapter 4: Making Direct C-Language Calls

This chapter introduces the Foreign Function Interface (FFI). In this chapter, you will learn what FFI is all about, what it's good for, and how to use it. This information in this chapter is important for developers interested in rapid custom prototyping using direct C-language calls.

In this chapter, not only do you learn about the background behind introducing FFI into the PHP language, but you also learn how to incorporate C-language structures and functions directly into your code. Although—as you will learn—this should not be done to achieve greater speed, it does give you the ability to incorporate any C-language libraries directly into your PHP application. This ability opens the doors to an entire world of functionality hitherto unavailable to PHP.

Topics covered in this chapter include the following:

  • Understanding FFI
  • Learning where to use FFI
  • Examining the FFI class
  • Using FFI in an application...
