Pro PHP Refactoring

Description

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 refactoring is and why you need to refactor code

* How to write unit and functional tests with PHPUnit and Selenium Remote Control (RC)

* How to refactor a large procedural application affected by many bad smells Who this book is for
