Jeremy Johnstone's Blog:
Enums in PHP
October 06, 2008 @ 07:56:08

In this new post Jeremy Johnstone looks at creating a class to add that's missing from the basic datatype set of the language - enums.

I stumbled across a blog post on how to implement Enums in PHP via userland code written by Jonathan Hohle. I liked the concept he had, but the implementation was a bit unappealing because it used eval() among other more minor issues. You shouldn't need to generate Enums at runtime, so I took that as a challenge to find a way to do it at compile time, thus making the code much more efficient.

His enums would support type hinting and would, ideally, be iterable. He gives the code he's worked up - a base class, another than extends it to make a basic enum structure and some handy changes to support comparisons. A few more changes (and a few other extended classes later) he has some pretty well functioning enums that can even bee iterated through.
