我要获得想要的结果最困难。我做了很多研究，但还没有得到。我对此很陌生，但是在发布此问题之前进行了研究。

好的，所以我有一个包含以下列的表：user_id，my_music，my_movies，my_weather，my_maps和my_news

除user_id之外的每一列都将具有1或0。我需要做的是找出数据库中针对特定用户的每一列所存储的值。

这是我到目前为止的内容-这是我的config.php：

// These variables define the connection information for your MySQL database
$username = "dbo12345";
$password = "xxxxxx";
$host = "db12345.db.123.com";
$dbname = "db12345";

$options = array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8');
try { $db = new PDO("mysql:host={$host};dbname={$dbname};charset=utf8", $username, $password, $options); }
catch(PDOException $ex){ die("Failed to connect to the database: " . $ex->getMessage());}
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
header('Content-Type: text/html; charset=utf-8');
session_start();

这是我的admin.php文件：

require("config.php"); 
if(empty($_SESSION['user'])) 
{
    header("Location: index.php");
    die("Redirecting to index.php"); 
}

$userid = $_SESSION['user']['id'];
$sql = "SELECT my_music, my_movies, my_weather, my_maps, my_news FROM user_preferences WHERE user_id = :userID"; //Note the removed semi-colon that was probably causing your error
$stmt = $db->prepare($sql);
$stmt = $db->bindParam(":userID", $userid);
$userid = $_SESSION['user']['id'];
$sql = "SELECT my_music, my_movies, my_weather, my_maps, my_news FROM user_preferences WHERE user_id = :userID"; //Note the removed semi-colon that was probably causing your error
$stmt = $db->prepare($sql);
$stmt->bindParam(":userID", $userid, PDO::PARAM_INT);
$stmt->execute();
$result = $stmt->fetch();

if ($result['my_music']) {
    $musicChecked = 'checked="checked"';
} else {
    $musicChecked = '';

}
if ($result['my_movies']) {
    $checked = 'checked="checked"';
} else {
    $checked = '';

}

我如何以不同的方式编写上面的代码？我知道有一种方法，但是我很难找到它。

根据上面的结果，我需要更新一些复选框，例如，如果数据库中my_music为1，则将复选框设置为“ checked”。所以我这样做：

<input type="checkbox" name="mymusic" id="mymusic" <? echo $musicChecked;?> />
<input type="checkbox" name="mymovies" id="mymovies" <? echo $moviesChecked;?> />

如果我需要添加更多信息，请告诉我。任何帮助都将不胜感激。
