问题描述

我想使用来自不同目录的菜单PHP文件。

I want to use a menu PHP file from different directories.

问题是当我调用该文件。示例：

The problem is when i call the file. Example:

Include menu.php from categories folder:http://localhost/admin/categories/categories/cars Include
Include menu.php from index folder: http://localhost/admin/categories/cars
Note that the menu file is not in a folder (index /).

问题是自动添加从菜单路径之前调用（包含）文件的目录。我不想要，我想要的路径是一样的所有文件夹，我从那里我没有menu.php

The problem is add automatically the directory from where i call (inlude) the file before the menu's path. I do not want that, i want the path to be the same for all folder from where i inlude the menu.php

看到这个例子。一线，有两类。 / categories / categories /\".

推荐答案

使用 include_once 可能会更方便，因为这样做只能包含一次。

Using include_once might be more convenient, as this guarantees that it's only included once.

此外，你最好使用绝对路径（ include /menu.php; ）。您正在使用相对路径（ includemenu.php; ）。

Furthermore, you'd be best off using absolute paths (include "/menu.php";). You are currently using a relative path (include "menu.php";).

由于PHP是一种服务器端语言，您可能需要从根路径中包含它，这意味着您会得到一个看起来像 /home/username/public_html/menu.php 。最简单的方法是包括你的menu.php，如下所示： include $ _SERVER ['DOCUMENT_ROOT']。/ menu.php; 。

As PHP is a serverside language, you may need to include it from the root-path, meaning that you'd get a path that looks like /home/username/public_html/menu.php. The easiest way to go about this would be to include your menu.php like this: include $_SERVER['DOCUMENT_ROOT']."/menu.php";.

要找到您的 menu.php 所在的确切路径（因此，请从您的路径中找出需要包含它），在你的menu.php中运行 echo $ _SERVER [SCRIPT_FILENAME]; ，因为它可能是不同于 $ _SERVER ['DOCUMENT_ROOT'] 。

To find the exact path where your menu.php is located (and thus, find out from what path you need to include it from), run echo $_SERVER["SCRIPT_FILENAME"]; in your menu.php, as it may be a different path than $_SERVER['DOCUMENT_ROOT'].
