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.

Taking control of serialization

There are many times when native PHP data needs to be stored in a file, or in a database table. The problem with current technology is that direct storage of complex PHP data such as objects or arrays is simply not possible, with some exceptions.

One way to overcome this limitation is to convert the object or array into a string. JSON (JavaScript Object Notation) is often chosen for this reason. Once the data has been converted into a string, it can easily be stored in any file or database. However, there is a problem with formatting objects with JSON. Although JSON is able to represent object properties well enough, it's incapable of directly restoring the original object's class and methods.

To address this deficiency, the PHP language includes two native functions, serialize() and unserialize(), that can easily convert objects or arrays into a string and restore them back to their original state. As wonderful as this sounds, there...
