PHP Enum - get rid of boilerplate mappings

Hey there. Just decided to put together a small package, that will help me to get rid of boilerplate mappings like public function getAll(): array // returns some static array of strings.

You just need to define constants, and my Enum\Enum class will do the rest for you, thanks to Reflection API.

Here is an example:

<?php
namespace App;

use Enum\Enum;

class Status extends Enum
{
    const ACTIVE   = 'active';
    const INACTIVE = 'inactive';
    const BLOCKED  = 'blocked';
}

$status = new Status();

$status->toArray(); // will return [ 'active' => 'active', 'inactive' => 'inactive', 'blocked' => 'blocked' ]
$status->hasValue('active'); // will return boolean
$status->hasKey('blocked'); // will return boolean

Enum's constructor has 2 parameters: $caseLower=true and $caseUpper=false.

If you want the case of array keys to be same as constants case - pass false as $caseLower.

$status = new Status(false);

If you want the case of array keys to be uppercase - pass false as $caseLower and true as $caseUpper.

$status = new Status(false, true);

We just created our custom type Enum. Now I can even use it to have better typed properties in my classes. For example:

<?php

namespace App;

use Enum\Enum;

class Person
{
    public int $identifier;
    public string $name;
    public Enum $status;
}

Now I know exactly what type has my $status and I know exactly how I should work with that type. I find this much better than using some raw arrays.
