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.

Securing SQLite databases with the authorizer

Many PHP developers prefer to use SQLite as their database engine rather than a separate database server such as PostgreSQL, MySQL, Oracle, or MongoDB. The reasons for using SQLite are many, but often come down to the following:

  • SQLite is a file-based database: You don't have to install a separate database server.
  • It's easy to distribute: The only requirement is that the target server needs to have the SQLite executable installed.
  • SQLite is lightweight: Since there's no constantly running server, it takes fewer resources.

That said, the downside is that it's not very scalable. If you have a fairly substantial amount of data to deal with, it's probably better to install a more powerful database server. The other potentially major drawback is that SQLite has no security, covered in the next subsection.
