PHP Software Engineering

Introduction

Typing out the expressions that form your computer program is only the beginning of building a healthy software system. This chapter discusses what should happen after you’ve written your initial code—tools for debugging and testing your software.

Explores the use of Xdebug, an open source PHP extension that allows for line-by-line debugging in real time.

Explore the world of unit testing in PHP, and show you how to turn your fixed bugs into a test suite that can help you ensure that once a bug is fixed, it stays fixed.

Introduces you to easy ways to set up a testing environment on your local computer, so that you can work in a sandbox environment without fear of breaking a production website while you’re trying to determine what’s gone wrong.

Lastly, explores the built-in web server that’s part of PHP 5.4.0 and later.
