遇到一些代码和字符串处理问题

语法错误，意外的文件结束......

有人可以帮忙吗？

<?php

    require("common.php");

    if(empty($_SESSION['user']))
    {

        header("Location: login.php");

        die("Redirecting to login.php");
    }

    $query = "
        SELECT
            id,
            username,
            email,
            gold
        FROM users
    ";

    try
    {

        $stmt = $db->prepare($query);
        $stmt->execute();
    }
    catch(PDOException $ex)
    {

        die("Failed to run query: " . $ex->getMessage());
    }


    $rows = $stmt->fetchAll();

mysqli_query($con,"UPDATE users SET gold = gold + 10
WHERE username= '".$_SESSION['user']['username']."');

header('Location: quests.php');
die();

?>

Answer 1

您忘了关闭引用的字符串：

mysqli_query($con,"UPDATE users SET gold = gold + 10
WHERE username= '".$_SESSION['user']['username']."'");

Answer 2

mysqli_query($con,"UPDATE users SET gold = gold + 10 WHERE username= '".$_SESSION['user']['username']."');

您忘记关闭引用"

应该是这样的：

mysqli_query($con,"UPDATE users SET gold = gold + 10 WHERE username= '".$_SESSION['user']['username']."'");

Answer 3

您错过了"行的结束mysqli_query：

."');

需要

."'");

如果你的编辑器没有使用语法高亮显示这一点，你应该使用不同的编辑器。

Answer 4

而不是

mysqli_query($con,"UPDATE users SET gold = gold + 10
WHERE username= '".$_SESSION['user']['username']."');

使用

mysqli_query($con,"UPDATE users SET gold = gold + 10
WHERE username= '".$_SESSION['user']['username']."'");

php＆amp; mysql语法错误：可能是字符串？
