Practical design patterns in PHP (Part 1)
summary
One-and-a-half day workshop covers about 10–12 design patterns with hands‑on PHP: uses Composer, moneyphp/money, ramsey/uuid and phpunit, plus an assertion library to guard inputs. Builds a small webshop domain (Product interface, PhysicalProduct, ComboProduct) implementing the Composite and later Decorator patterns, writes PHPUnit tests that run and pass, and shows factories/value‑objects (Money, UID, Weight) and how composition replaces brittle inheritance.
