在php中找到一个4个目录的文件 [英] finding a file in php that is 4 directories up

问题描述

我找不到文件，即使使用多个 ../ 查找文件：

I cannot locate the file even when using multiple ../ to find the file:

root -> public -> secure -> lock  -> login / "data.php"
                            panel -> data -> list / "list.php"

我想包括 data.php 与我的 list.php 并尝试执行以下操作来包含数据：

I want to include data.php with my list.php and tried doing the following to include the data:

include("../../../../lock/login/data.php");
include("../../../lock/login/data.php");
and also
include("../../lock/login/data.php");

然而，这似乎不起作用，但如果我把它放在$ code > list.php 并执行以下操作，它读取数据就好了：

However, this doesn't seem to work, but if I place it beside list.php and do the following, it reads the data just fine:

include("data.php");

我的代码做错了什么，什么是更好的方法来执行？ >

What am I doing wrong with my code and what is a better way to execute this?

推荐答案

学习使用：

__FILE__; // for your current file path
dirname(__FILE__) or __DIR__; // for your current file parent folder
$_SERVER['DOCUMENT_ROOT']; // for your sites inception folder, your pivotal point

这应该让你的方式。 然后你可以：

This should get you on your way. Then you can:

include __DIR__.'/../file-REALLY-relative-to-directory-of-edit-file.php';
include $_SERVER['DOCUMENT_ROOT'].'/absolute-path-reliable-for-your-site.php';

永远不会相关包含类似 （当前目录可以更改并打破你的世界）：

include 'an-unreliable-NOT-REALLY-relative-file.php';
