高級數組排序PHP

Question

我正在創建一個紙牌遊戲，一個頁面創建遊戲並將每個玩家的所有紙牌插入到MySQL數據庫中。 c1，c2，c3 ...等是由您選擇的隨機卡存儲的。

因此，card1將以c1的形式存儲在數據庫中，其餘12張卡片將作爲c1存儲在數據庫中。

但

後的卡從DATABSE返回遊戲頁面上，他們通過一系列與卡中的圖片進行組織。然後通過兩個數組顯示它們。

  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是圖片分類器。

$fetch是從數據庫返回的數組。

  $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); 

下面這段代碼爲我提供了正是我需要的print_r回報

Array ([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) 有組織的上升，但後來當我顯示卡，我無法弄清楚如何讓他們的順序運行，因爲關鍵是數據庫中的列名，以及我在顯示中無法要求的值。

所以我的基本問題是，我如何排序卡，以便他們運行通過我當前的陣列中排序圖片升序卡？

如果需要;

  $cards = array(
        "0" => "<img src=\"cards/dead.png\"/>", 
        "1" => "<img src=\"cards/2_of_spades.png\"/>", 
        "2" => "<img src=\"cards/3_of_spades.png\"/>", 
        "3" => "<img src=\"cards/4_of_spades.png\"/>",

Answer 1

使用foreach（doco here）應以正確的順序返回它們。

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

凡$cardId是關鍵（例如 'C1'）和$card是該卡的ID值（例如3）。
