php - 高级数组排序 PHP

Question

我正在创建一个纸牌游戏，一个页面创建游戏并将每个玩家的所有纸牌插入 MySQL 数据库。 c1,c2,c3...依此类推由为您选择的随机卡存储。

因此，card1 将作为整数存储在数据库中，如 c1，其余 12 张卡片依此类推。

但是

卡片从数据库返回到游戏页面后，会经过一个数组，用卡片图片进行组织。然后它们通过两个数组显示。

            echo '<form input="index.php" method="post">';
            echo $cards[$fetch['c1']].'<input class="check" type="checkbox" name="c1c">';
            echo $cards[$fetch['c2']].'<input class="check" type="checkbox" name="c2c">';
            echo $cards[$fetch['c3']].'<input class="check" type="checkbox" name="c3c">';
            echo $cards[$fetch['c4']].'<input class="check" type="checkbox" name="c4c">';
            echo $cards[$fetch['c5']].'<input class="check" type="checkbox" name="c5c">';
            echo $cards[$fetch['c6']].'<input class="check" type="checkbox" name="c6c">';
            echo $cards[$fetch['c7']].'<input class="check" type="checkbox" name="c7c">';
            echo $cards[$fetch['c8']].'<input class="check" type="checkbox" name="c8c">';
            echo $cards[$fetch['c9']].'<input class="check" type="checkbox" name="c9c">';
            echo $cards[$fetch['c10']].'<input class="check" type="checkbox" name="c10c">';
            echo $cards[$fetch['c11']].'<input class="check" type="checkbox" name="c11c">';
            echo $cards[$fetch['c12']].'<input class="check" type="checkbox" name="c12c">';
            echo $cards[$fetch['c13']].'<input class="check" type="checkbox" name="c13c">';
            print_r($fetch);

$cards 是图片分类器。

$fetch 是从数据库返回的数组。

            $query = "SELECT c1,c2,c3,c4,c5,c6,c7,c8,c9,c10,c11,c12,c13 FROM games WHERE comp = 0";
            $stmt = $db->prepare($query);
            $stmt->execute();

            $fetch = $stmt->fetch(PDO::FETCH_ASSOC);

            asort($fetch);

现在这段代码为我提供了我所需要的，print_r 返回

数组 ( [c9] => 3 [c5] => 6 [c10] => 8 [c11] => 13 [c13] => 15 [c3] => 16 [c2] => 18 [c1] => 19 [c4] => 24 [c8] => 40 [c12] => 44 [c7] => 45 [c6] => 47)有组织的升序，但是当我显示卡片时，我不知道如何让它们按那个顺序运行，因为键是数据库中的列名，而我不能在显示中要求的值。

所以我的基本问题是，我如何对卡片进行排序，以便它们遍历我当前的数组以将图片按升序排列到卡片？

如果需要；

            $cards = array(
                    "0" => "<img src=\"cards/dead.png\"/>",
                    "1" => "<img src=\"cards/2_of_spades.png\"/>",

Answer 1

使用 foreach ( doco here ) 应该以正确的顺序返回它们。

foreach($fetch as $cardId => $card) {
    echo 'CardID: ' . $cardId . '<br>';
    echo 'Card: ' . $cards[$card] . '<br>';
}

其中 $cardId 是 key (例如“c1”)，$card 是卡的 ID 值(例如 3)。
