嗨，我正在我的网站上创建一个论坛。我将相关文件存储在我的服务器上：“includes/mod_forum/foum”
我存储在初始目录中的 index.php 页面（在“inlcudes/../..”之前）具有指向与 index.php 相同的本地目录中的文件 forum.php 的链接。
在文件 forum.php 我设置了一个包含函数：“ <?php include('includes/mod_forum/forum/index.php'); ?>”
index.php 文件和存储在“includes/mod_forum/forum/”中的名为 post.php 的文件都需要连接到我的 sql 数据库。
设置数据库凭据的文件存储在“includes/_config/connection.php”中。
当我访问直接存储在“includes/mod_forum/forum/”中的 index.php 文件时，它发现 connection.php 文件正常并连接到我的数据库，但是当我访问本地/主目录中的 forum.php（在“inlcudes/”之前../.."）它找不到连接数据库的connection.php文件。
任何想法为什么会这样？
希望我已经解释清楚了。
这是我得到的错误：
