README

This library extends myclabs/php-enum with ability to compare enums by their identity (if static methods are used to create them).

Usage

1. Require this package:

   $ composer require pamil/enum

2. Create your enum:

   <?php
   
   use Pamil\Enum\Enum;
   
   /**
    * @method static static active()
    * @method static static inactive()
    */
   final class SampleEnum extends Enum
   {
       protected const active = 1;
       protected const inactive = 2;
   }

3. Compare your enums by identity:

   var_dump(SampleEnum::active() === SampleEnum::active()); // true

Caveats

• It does not work when creating enums by the constructor:

  var_dump(new SampleEnum(1) === SampleEnum::active()); // false

• It does not work when you deserialise serialised enums:

  var_dump(unserialize(serialize(SampleEnum::active())) === SampleEnum::active());
