Ordinary enum type implementation for PHP

OrdinaryEnum

'Ordinary' enum it's another implementation for PHP, but with one difference - simple as it's possible.

Where to and why to use

I recommend to use when need to construct some think in strict way, so for that comes Enum type. You define in some class in constructor or method a Enum class with will wait a const value form child of enum class. In that case you will control code and reduce dummy switch\if's in your code to validate states or string values etc., _(*1)

How it works and how to use

Easy as possible, you crates some class and extends for Orinary's Enum class, then defines needed const values. Like that:, _(*2)

class StoreEnum extends Enum
{
  public const __default = self::GROCERY;
  public const GROCERY   = Grocery::class;
  public const COSMETIC  = Cosmetic::class;
}

So as you see it's easy to create list of controlled values, so it will help ya to keep cleaner your code with dependencies., _(*3)

Example:, _(*4)

...
// Let's imagine you have fabric with stores
$fruitStore = $this->storeFabric()->create(StoreEnum::GROCERY);
...
// Now let's see how can be used Enum in create method
...
public function create(Enum $storeType): StoreInterface
{
  try {
    $storeType = new StoreEnum($type);
  } catch(InvalidEnumTypeException $e) {
    throw new \RuntimeException('Unable to create store from factory');
  }

   return new $storeType->getValue();
}
...

That's it, you define objects and provide them or handling errors, light and simple., _(*5)

P.s. From me, that implementation I'm using in different web services and client library's to keep more controllable code and reduce errors with ungiven values as expected., _(*6)
