Download or read book Pro PHP Refactoring written by Francesco Trucchia and published by Apress. This book was released on 2011-01-10 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
