PHP Objects, Patterns, and Practice

If that's a problem, well, it's the kind you want to have. Especially if you have the tools at hand to navigate the risks and opportunities that present themselves. PHP continues to tick items off the object-oriented developer's wish list. Since the last edition of this book, we have seen namespaces make it into the language, late static binding, anonymous functions, and closures (if those don't yet mean anything to you, don't worry, they're all covered by this book). PHP is an active language, constantly evolving to meet the needs of its users. For a developer, this presents some interesting challenges. Not least, the tension between a stable codebase and the desire to take advantage of the goodies that every new release brings. With a good suite of tests, preferably run automatically, tools for collaboration, and an easily installed system, you can improve the design of your code, play with new features, and be fairly sure that you're not breaking stuff.
