我的 MySQL 查询再次出现问题。我正在尝试使用 $_GET 变量执行查询。这是我的代码。非常感谢，非常感谢您的回答。

如果有人认为我的问题不正确，请不要否决我的问题，请编辑它或告诉我编辑它。

非常感谢。这是代码。

 $Status = $_GET['status'];
 $User = $_GET['user'];

    require('./connect.php');
    $query = "SELECT * FROM users ORDER BY id ASC";
    $result = mysqli_query($con, $query);
    $numrows = mysqli_num_rows($result);
 if ($numrows > 0) {
        echo '<table class="table" border="1">
        <tr style="background-color: #0DF; color: #222; font-weight:bold;">
            <td>ID:</td>
            <td>User Name:</td>
            <td>Email:</td>

您在 while 循环内定义 $dbuser，因此它被设置为循环上次迭代中的用户名。根据您的代码，我不确定 $dbuser 应该是什么，根据您的代码判断......
