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 symfonyponentserializerormalizerdenormalizerinterface;use symfonyponentserializerormalizerormalizerinterface;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(); }}
