Sustainable PHP: The Quest

This month, "The Quest," takes us on a quest to avoid the Big Ball of Mud. We'll begin by learning what the Big Ball of Mud is. Our quest will discover that Domain-Driven Design (DDD) can be our solution, but the current state of the art does not quite (to the best of my knowledge) "bridge the gap" between pure DDD and our typical framework-based PHP development. Next month, in "Build a Composite," we'll explicitly bridge that gap with PHP code using a standard PHP framework.
