Migrate legacy string/integer constants to PHP 8.1+ backed enums for type-safe domain modeling. Covers validation with ::tryFrom(), exhaustive match expressions, and Doctrine ORM mapping.
PHP 8.1 backed enums turn scattered magic strings into a closed set of type-safe values. Learn the migration path, a worked repository example, and the serialization trade-offs.
String constants in PHP are error‑prone. PHP 8.1’s backed enums give you type safety, clearer intent, and easier persistence. This blog walks through the syntax, shows a real‑world order‑status refactor, and explains the trade‑offs you’ll face.
Learn when to use pure versus backed PHP enums, how to model domain states, persist them with Doctrine, and avoid common pitfalls.
String status columns accept typos and invalid states. A PHP 8.1 backed enum makes the valid set explicit, with conversion at the edges and real trade-offs to weigh.
