php实现扑克

实现扑克牌的PHP代码示例

以下是一个简单的PHP实现扑克牌生成、洗牌和发牌的示例代码：

生成一副扑克牌

$suits = ['♥', '♦', '♣', '♠'];
$values = ['2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A'];

$deck = [];
foreach ($suits as $suit) {
    foreach ($values as $value) {
        $deck[] = $suit . $value;
    }
}

洗牌功能实现

function shuffleDeck(&$deck) {
    $count = count($deck);
    for ($i = $count - 1; $i > 0; $i--) {
        $j = random_int(0, $i);
        [$deck[$i], $deck[$j]] = [$deck[$j], $deck[$i]];
    }
}

shuffleDeck($deck);

发牌功能实现

function dealCards(&$deck, $numPlayers, $cardsPerPlayer) {
    $hands = array_fill(0, $numPlayers, []);

    for ($i = 0; $i < $cardsPerPlayer; $i++) {
        for ($j = 0; $j < $numPlayers; $j++) {
            if (!empty($deck)) {
                $hands[$j][] = array_shift($deck);
            }
        }
    }

    return $hands;
}

$players = 4;
$cardsPerPlayer = 5;
$playerHands = dealCards($deck, $players, $cardsPerPlayer);

扑克牌游戏类实现

class PokerGame {
    private $deck;
    private $suits = ['♥', '♦', '♣', '♠'];
    private $values = ['2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A'];

    public function __construct() {
        $this->initializeDeck();
    }

    private function initializeDeck() {
        $this->deck = [];
        foreach ($this->suits as $suit) {
            foreach ($this->values as $value) {
                $this->deck[] = ['suit' => $suit, 'value' => $value];
            }
        }
    }

    public function shuffle() {
        shuffle($this->deck);
    }

    public function deal($numCards) {
        $cards = [];
        for ($i = 0; $i < $numCards; $i++) {
            if (!empty($this->deck)) {
                $cards[] = array_shift($this->deck);
            }
        }
        return $cards;
    }

    public function getDeckCount() {
        return count($this->deck);
    }
}

$game = new PokerGame();
$game->shuffle();
$hand = $game->deal(5);

扑克牌点数计算

function calculateHandValue($hand) {
    $values = [
        '2' => 2, '3' => 3, '4' => 4, '5' => 5,
        '6' => 6, '7' => 7, '8' => 8, '9' => 9,
        '10' => 10, 'J' => 10, 'Q' => 10, 'K' => 10, 'A' => 11
    ];

    $total = 0;
    $aces = 0;

    foreach ($hand as $card) {
        $value = is_array($card) ? $card['value'] : substr($card, 1);
        $total += $values[$value];
        if ($value === 'A') {
            $aces++;
        }
    }

    while ($total > 21 && $aces > 0) {
        $total -= 10;
        $aces--;
    }

    return $total;
}

这些代码示例展示了如何在PHP中实现基本的扑克牌功能，包括生成牌组、洗牌、发牌和计算牌面点数等功能。可以根据具体游戏需求进一步扩展这些基础功能。
