In addition to discussing the latest developments in build, test, and continuous integration, this section keeps pace with best practice in version control by focusing on Git, increasingly the developer's system of choice. It also explores strategies for automated testing and build. The section shows how to manage multiple developers and releases with git, how to build and install using Phing and PEAR. The last segment of the book covers the tools and practices that can help turn great code into a successful project. It covers many of the classic design patterns and includes chapters on enterprise and database patterns. The section describes the design principles that make patterns powerful. These describe common problems and their solutions. The next section is devoted to design patterns. This edition introduces new object relevant features such as traits, reflection extension additions, callable type hinting, improvements to exception handling, and many smaller language enhancements. It also introduces some principles of design. These provide the fundamentals of the PHP's support for objects. It introduces key topics including class declaration, inheritance, reflection and much more. The book begins by covering PHP's object-oriented features.
