php问题包括一个包含文件

I got a problem about including a included file in PHP.

我在PHP中包含一个包含文件时遇到了问题。

Project

项目

functions(folder) has a.php
functions（folder）有一个.php
xml(folder) has b.xml
xml（文件夹）有b.xml
index.php
的index.php

This is my project structure(sorry about that, I can't post images). I try to use "index.php" to include "a.php" while "a.php" is using "b.xml"

这是我的项目结构（对不起，我无法发布图片）。我尝试使用“index.php”包含“a.php”，而“a.php”使用“b.xml”

this is what i did on XAMPP and it works perfectly:

这就是我在XAMPP上所做的，它完美地运作：

in index.php I wrote: include 'functions/a.php';

在index.php中我写道：include'function / a.php';

in a.php I wrote: $xml->load('xml/b.xml');

在a.php中我写道：$ xml-> load（'xml / b.xml'）;

However if I copy these to my Uni's apache server, it can't open this b.xml. This is not permission because when i change to absolute path it works...

但是，如果我将这些复制到我的Uni的apache服务器，则无法打开此b.xml。这不是许可，因为当我改为绝对路径时，它有效......

Thank you guys in advance:-)

提前谢谢你们:-)

3 个解决方案

#1

in a.php you should refer to ../xml/b.xml if you use include thing is, it depeneds on when $xml->load() is defined. if it's your own code then put the path relative to the definition. otherwise "../xml/b.xml" should work.

在a.php中你应该引用../xml/b.xml如果你使用include thing is，它取决于定义$ xml-> load（）的时候。如果它是您自己的代码，则将路径相对于定义。否则“../xml/b.xml”应该有效。

you can always to $_SERVER['DOCUMENT_ROOT'], but i myself like defining directories as constants (with absolute path) and using them around the project.

你可以随时使用$ _SERVER ['DOCUMENT_ROOT']，但我自己喜欢将目录定义为常量（使用绝对路径）并在项目周围使用它们。

define('DIR_ROOT', $_SERVER['DOCUMENT_ROOT'] . '/');
define('DIR_FUNCTIONS', DIR_ROOT . 'functions/');
define('DIR_XML', DIR_ROOT . 'xml/');

#2

Try using set_include_path() to set the include path to your application's root directory; then you should be able to include files relative to this path.

尝试使用set_include_path（）设置应用程序根目录的包含路径;那么你应该能够包含相对于这个路径的文件。

#3

It's always better to use absolute paths, even if you have to construct it (e.g. $XML_PATH = $PATH_TO_BASE . 'xml/b.xml'; )

使用绝对路径总是更好，即使你必须构造它（例如$ XML_PATH = $ PATH_TO_BASE。'xml / b.xml';）

If you can't do that, you should add xml's parent to your path.

如果您不能这样做，则应将xml的父级添加到路径中。
