英文:
PHP file directory not found
问题
I've translated the code as you requested. Here's the translated code:
我正在制作一个简单的简历类型的网站，可以在其中编辑我的个人资料。我遇到的问题是，我有一个 header.php 文件，其中包含所有导航按钮。我将该 header 文件包含到每个页面中。
当我在我的个人资料页面上单击“编辑”个人资料时，它会将我带到另一个页面，启用了输入字段以编辑我的个人资料。问题是，当我在编辑个人资料页面上（位于子文件夹中）并使用“../header.php”包含根时，导航选项不起作用，因为在 header.php 中，所有文件都在根文件夹中，但当我从子文件夹包含头文件并尝试导航时，它尝试在子文件夹中查找文件，但该文件不存在。
它应该让我通过正常方式浏览页面，即通过返回一个目录，但我无法制作硬编码的解决方案，因为我的页眉位于根文件夹中。
以下是我的代码：
header.php：
<?php
// 需要数据库文件以进行连接。
require 'resources/database/mysqli_connect.php';
// 启动会话。
session_start();
$rank = 0;
// 如果会话不为空，分配变量并运行查询。
if (!empty($_SESSION["id"])) {
$id = $_SESSION["id"];
$rank = $_SESSION["rank"];
$result = mysqli_query($conn, "SELECT * FROM users WHERE id = $id");
$row = mysqli_fetch_assoc($result);
}
?>

I'm making a simple resume-type website in which I can edit my profile. The issue that I am having is, I have a header.php file which has all the navigation buttons. I'm including that header file into every page which I have.
When I go on my profile and click 'Edit' profile, it takes me to another page with input fields enabled to edit my profile. The problem is, when I am on the edit profile page (which is in a subfolder), and it has included root using '../header.php', the navigation options are not working because on header.php, all files are in the root folder, but when I'm including the header file from a subfolder and trying to navigate, it's not going to the root folder, it's trying to find the file in the subfolder which doesn't exist.
It should let me navigate through the pages as normal by going back a directory, but I can't make a hard-coded solution as my header is in the root folder.
Here's my code:
header.php:
<?php
// requires database file for connection.
require 'resources/database/mysqli_connect.php';
// Starts the session.
session_start();
$rank = 0;
// If session is not empty, assigns variables and runs the query.
if(!empty($_SESSION["id"])){
$id = $_SESSION["id"];
$rank = $_SESSION["rank"];
$result = mysqli_query($conn, "SELECT * FROM users WHERE id = $id");
$row = mysqli_fetch_assoc($result);
}
?>

You should not use a relative path to link to other files. If you use the relative path, you rely on your current environment. However, your environment can change. So you may have to change your code. As an example, if you move your file to a subdirectory in another subdirectory of the subdirectory, that means adjusting the code...
Instead, I would use the absolute path. This links the complete path to your file, including your environment.
This can be slower but is probably not critical for your project. It has several advantages, for example, you don't have to change the code, and it's much more efficient when you collaborate with other programmers who may be working in different environments.
Maybe see this answer here for the absolute PATH: https://stackoverflow.com/a/11604489/21940880
