PHP is experiencing a renaissance, though it may be difficult to tell with all of the outdated PHP tutorials online. With this practical guide, you’ll learn how PHP has become a full-featured, mature language with object-orientation, namespaces, and a growing collection of reusable component libraries.

Author Josh Lockhart—creator of PHP The Right Way, a popular initiative to encourage PHP best practices—reveals these new language features in action. You’ll learn best practices for application architecture and planning, databases, security, testing, debugging, and deployment. If you have a basic understanding of PHP and want to bolster your skills, this is your book.

Discover how to find, use, and create PHP components
Follow best practices for application security, working with databases, errors and exceptions, and more
Learn tools and techniques for deploying, tuning, testing, and profiling your PHP applications
Explore Facebook’s HVVM and Hack language implementations—and how they affect modern PHP
Build a local development environment that closely matches your production server
