我最近一直在与 verbs 和 livewire 合作，并认为尝试创建一些我喜欢玩的纸牌游戏是一个有趣的实验。

为了促进这一点，我需要定义一副卡片，我可以在之后从事的任何项目中使用它。

一副牌需要包含 card、deck 和 cardcollection 类。一张牌应有花色和数值，一副牌应由 52 张牌组成。因为花色和数值都是为一副牌定义的，所以我可以使用枚举来表示牌的属性。

cardcollection 类允许我以 verbs 状态安全地存储卡片集合。

<?php// cards/enums/suit.phpdeclare(strict_types=1);namespace cardsenums;enum suit: string{    case clubs = 'clubs';    case diamonds = 'diamonds';    case hearts = 'hearts';    case spades = 'spades';}

<?php// cards/enums/value.phpdeclare(strict_types=1);namespace cardsenums;enum value: string{    case two = 'two';    case three = 'three';    case four = 'four';    case five = 'five';    case six = 'six';    case seven = 'seven';    case eight = 'eight';    case nine = 'nine';    case ten = 'ten';    case jack = 'jack';    case queen = 'queen';    case king = 'king';    case ace = 'ace';}

<?php// cards/card.phpdeclare(strict_types=1);namespace cards;use cardsenumssuit;use cardsenumsalue;final readonly class card{    public function __construct(        public suit $suit,        public value $value,    ) {}}

<?php// cards/cardcollection.phpdeclare(strict_types=1);namespace cards;use illuminatesupportcollection;use symfonycomponentserializerormalizerdenormalizerinterface;use symfonycomponentserializerormalizerormalizerinterface;use thunkerbsserializedbyverbs;class cardcollection extends collection implements serializedbyverbs{    public static function deserializeforverbs(mixed $data, denormalizerinterface $denormalizer): static    {        return static::make($data)            ->map(fn($serialized) => card::deserializeforverbs($serialized, $denormalizer));    }    public function serializeforverbs(normalizerinterface $normalizer): string|array    {        return $this->map(fn(card $card) => $card->serializeforverbs($normalizer))->tojson();    }}

<?php// Cards/Deck.phpdeclare(strict_types=1);namespace Cards;use CardsEnumsSuit;use CardsEnumsValue;final class Deck{    public CardCollection $cards;    public function __construct()    {        $this->cards = CardCollection::make([]);        collect(CardSuit::cases())            ->each(function (CardSuit $suit): void {                collect(CardValue::cases())                    ->each(function (CardValue $value) use ($suit): void {                        $this->cards->push(new Card($suit, $value));                    });            });        $this->shuffle();    }    public function shuffle(): void    {        $this->cards = $this->cards            ->shuffle()            ->reverse();    }    public function deal(): ?Card    {        if (0 === $this->cards->count()) {            return null;        }        return $this->cards->pop();    }    public function remainingCards(): int    {        return $this->cards->count();    }}
