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.

Speeding up array handling

Arrays are a vital part of any PHP program. Indeed, dealing with arrays is unavoidable as much of the real-world data your program handles day to day arrives in the form of an array. One example is data from an HTML form posting. The data ends up in either $_GET or $_POST as an array.

In this section, we'll introduce you to a little-known class included with the SPL: the SplFixedArray class. Migrating your data from a standard array over to a SplFixedArray instance will not only improve performance but requires significantly less memory as well. Learning how to take advantage of the techniques covered in this chapter can have a substantial impact on the speed and efficiency of any program code currently using arrays with a massive amount of data.

Working with SplFixedArray in PHP 8

The SplFixedArray class, introduced in PHP 5.3, is literally an object that acts like an array. Unlike ArrayObject, however, this class requires you to place a hard...
