Kind of like the Laravel Lottery helper, but with unlimited outcomes

Raffle.php

<?php

use Illuminate\Support\Collection;

class Raffle
{
    private int $total = 0;
    private int $current = 0;
    private Collection $entries;

    public function __construct()
    {
        $this->entries = collect();
    }

    public static function make(): Raffle
    {
        return new self();
    }

    public function add(int $tickets, callable $callback): static
    {
        $this->entries->push([
            'win' => range($this->current + 1, $this->current + $tickets),
            'callback' => $callback,
        ]);
        $this->current += $tickets;
        $this->total += $tickets;
        return $this;
    }

    public function run()
    {
        $selected = $this->entries->pluck('win')->flatten()->random(1)->first();
        $winner = $this->entries->filter(fn($entry) => in_array($selected, $entry['win'], true))->first();
        return $winner['callback']();
    }
}

Raffle::make()
  ->add(10, fn() => "this")
  ->add(10, fn() => "that")
  ->add(20, fn() => "the other thing")
  ->run();
