Question

我无法打印$ userLabel（$ _SESSION ['nickname']）。我在本地主机上使用phpmyadmin和apache。

我似乎无法弄清楚问题。我在phpmyadmin中创建了一行，我知道它在第4行。这可能是一个错误的方法还是什么？我是PHP的新手，并试图弄清楚。任何解决方案或附加帮助都会很棒！谢谢！

登录：

if($_POST['submit']) {
    include_once("connection.php");
    $username = strip_tags($_POST['username']);
    $password = strip_tags($_POST['password']);

    $sql = "SELECT id, username, password, nickname FROM users WHERE username = '$username' AND activated = '1' LIMIT 1";
    $query = mysqli_query($connect, $sql);

    if ($query) {
        $row = mysqli_fetch_row($query);
        $userId = $row[0];
        $dbUsername = $row[1];
        $dbPassword = $row[2];
        $userLabel = $row[4];
    }

    if ($username == $dbUsername && $password == $dbPassword) {
        $_SESSION['username'] = $username;
        $_SESSION['id'] = $userId;
        $_SESSION['nickname'] = $userLabel;


        header('Location: user.php');
    } 
    else {
        echo "Error: password mismatch.";
    }

我的PHP会话变量出了什么问题？
