That looks like it falls into my first category: the actual value of the constant doesn't matter, you just need to be able to compare against it later. That makes it a perfect use case for PHP 8.1's new "enum" type, where you'll be able to declare this: enum Feature {

     case FEATURE_FLAG_WITH_SOME_LONG_NAME;
     case FEATURE_SOME_ANOTHER_COOL_FEATURE;

} You can then even define the "isEnabled" function so that it only accepts Feature values, not strings (i.e. "public function isEnabled(Feature $feature): bool { ... }" instead of "public function isEnabled(string $feature): bool { ... }"). If you're not familiar with the new enums, the best documentation at the moment is probably the RFC which proposed them: https://wiki.php.net/rfc/enumerations I'm really looking forward to using them :) Regards, -- Rowan Tommins [IMSoP]
