I’ve been working on a project lately where I’m rolling my own basic role-based access control (RBAC) system. In experimenting with different ways to handle the role definitions, I though that it’d be nice to have a basic enum() function or construct, as a quick, convenient way to define a set of constants. There’s this option:
<?php define('ADMIN', 0); define('MODERATOR', 1); define('EDITOR', 2);
but that isn’t exactly succinct. I’d rather have something like this:
<?php enum('ADMIN', 'MODERATOR', 'EDITOR'); // ADMIN == 0 // MODERATOR == 1 // etc.
