Still trying to learn how to use these well.

<?php

namespace App\InvoiceSystems;

enum Status : string
{

    case Open = "1";
    case PastDue = "2";
    case Paid = "6";
    case Archived = "3";



    public static function getName(string $value) : string {
        $class = new \ReflectionClass(__CLASS__);
        $constants = $class->getConstants();

        $name = collect($constants)->first(function($item) use ($value) {
            return $item->value === $value;
        });

        if($name === false) {
            throw new \InvalidArgumentException("No enum constant with value '$value'");
        }

        return str($name->name)->headline();
    }


}
