我收到这个即使我的配置文件是这样:

I'm getting this error above on localhost even if my config file is like this:

<?php

    define("DB_HOST", "localhost");
    define("DB_USER", "root");
    define("DB_PASSWORD", "");
    define("DB_DATABASE", "databasename");

    $db = mysqli_connect(DB_SERVER, DB_USERNAME, DB_PASSWORD, DB_DATABASE);

?>

以前工作,但现在不再工作了。这个代码有什么问题,还是现在不工作? 是我目前正在开发的教程。

This used to work, but now it doesn't anymore. Is there any problem with this code or is it not working now? This is the tutorial I am working on right now.

推荐答案

用户名,主机和密码的组合不允许连接到服务器。验证服务器上的权限表(重新载入授权,如果需要),并连接到正确的服务器。

That combination of username, host, and password is not allowed to connect to the server. Verify the permission tables (reloading grants if required) on the server and that you're connecting to the correct server.
