I wrote a simple solution using ... PHP! (classes and type hinting).
This package can help you, https://github.com/divengine/enum. It is a simple
class, but the concept is more important!. Also you can build taxonomies of enums.
$ composer require divengine\enum;
<?php
use divengine\enum;
class Temperature extends enum {}
class ExtremeTemperature extends Temperature {}
class FIRE extends ExtremeTemperature {}
class ICE extends ExtremeTemperature {}
class NormalTemperature extends Temperature {}
class HOT extends NormalTemperature {}
class COOL extends NormalTemperature {}
class COLD extends NormalTemperature {}
function WhatShouldIdo(Temperature $temperature) {
...
if ($temperature instanceof HOT) { ... }
if ($temperature == HOT::class) { ... }
...
}
WhatShouldIdo(new HOT());
