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.

A block of code is set as follows:

// /repo/ch01/php7_prop_reduce.php
class Test {
 protected $id = 0;
 protected $token = 0;
 protected $name = '';o

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

$result = match(<EXPRESSION>) {
   [<ITEM> => <EXPRESSION>,]
    default => <DEFAULT EXPRESSION>

Any command-line input or output is written as follows:

Fatal error: Uncaught TypeError: Cannot assign string to property Test::$token of type int in /repo/ch01/php8_prop_danger.php:12
