定义根路径 [英] Defining a Root Path

问题描述

我正在寻找一种方法来将配置变量定义为网站的根路径。定义它的最好方法是什么。我正在使用Codeigniter。

I'm looking for a way to define a config variable as being the root path of my website. What's the nicest way to define this. I am using Codeigniter.

$config['root_path'] = ?

这是我的config文件夹中的site_config文件。

This is for my site_config file in my config folder.

/
/dev
/dev/application
/dev/application
/dev/application/config
/dev/application/config/site_config.php
/dev/system/
/dev/assets/
/public_html

推荐答案

我认为

$config['root_path'] = $_SERVER['DOCUMENT_ROOT'];

将为您提供所需的内容，而不管哪个脚本从何处调用它。

will give you what you're looking for, regardless of which script calls it from where.

另一方面，我对Codeigniter的使用经验大约为零，这可能会对我的建议产生负面影响。

On the other hand, I have approximately zero experience with codeigniter, which could negatively impact the efficacy of my suggestion.
