Many businesses and organizations depend on older high-value PHP software that risks abandonment because it is impossible to maintain. The reasons for this may be that the software is not well designed; there is only one developer (the one who created the system) who can develop it because he didn’t use common design patterns and documentation; or the code is procedural, not object oriented. With this book, you’ll learn to identify problem code and refactor it to create more effective applications using test-driven design.

What you’ll learn

• What refactoring is and why you need to refactor code
• What test-driven design is and why you need to test your code
• How to write unit and functional tests with PHPUnit and Selenium Remote Control (RC)
• How to detect “bad smells” in PHP code, and refactor them using test-driven design
• How to refactor a large procedural application affected by many bad smells

Who is this book for?

This book is for PHP developers, businesses, and developers relying on legacy PHP apps.
