php实现扑克

PHP实现扑克牌功能

创建一副标准的52张扑克牌（不含大小王）的PHP实现方法：

$suits = ['Spades', 'Hearts', 'Diamonds', 'Clubs'];
$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' => $suit, 'value' => $value];
    }
}

洗牌功能实现

使用PHP内置的shuffle函数随机打乱牌组：

shuffle($deck);

发牌功能实现

从洗好的牌组中分发指定数量的牌：

function dealCards(&$deck, $numCards) {
    $hand = [];
    for ($i = 0; $i < $numCards; $i++) {
        $hand[] = array_shift($deck);
    }
    return $hand;
}

牌面显示格式化

将牌面信息转换为更友好的显示格式：

function formatCard($card) {
    $suitSymbols = [
        'Spades' => '♠',
        'Hearts' => '♥',
        'Diamonds' => '♦',
        'Clubs' => '♣'
    ];
    return $card['value'] . $suitSymbols[$card['suit']];
}

完整示例使用

创建、洗牌并分发5张牌：

$suits = ['Spades', 'Hearts', 'Diamonds', 'Clubs'];
$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' => $suit, 'value' => $value];
    }
}

shuffle($deck);

$hand = dealCards($deck, 5);

foreach ($hand as $card) {
    echo formatCard($card) . "\n";
}

扑克牌游戏扩展功能

计算牌面点数（适用于21点游戏）：

function calculateHandValue($hand) {
    $value = 0;
    $aces = 0;

    foreach ($hand as $card) {
        if (is_numeric($card['value'])) {
            $value += $card['value'];
        } elseif ($card['value'] == 'A') {
            $value += 11;
            $aces++;
        } else {
            $value += 10;
        }
    }

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

    return $value;
}

牌组重置功能

当牌组剩余牌数不足时重新生成并洗牌：

function resetDeck(&$deck) {
    global $suits, $values;
    $deck = [];
    foreach ($suits as $suit) {
        foreach ($values as $value) {
            $deck[] = ['suit' => $suit, 'value' => $value];
        }
    }
    shuffle($deck);
}
