如何获取public_html文件夹的绝对路径? [英] How to get the absolute path to the public_html folder?

问题描述

$_SERVER['DOCUMENT_ROOT']

问题是我必须编写一个脚本，该脚本可以位于public_html文件夹或public_html文件夹的子文件夹中.该脚本应将上传的文件保存到public_html目录(例如图片)内的文件夹中.换句话说，让我们说我的文件是test.php，它的路径是

The problem is that I have to write a script which can be in the public_html folder or a sub-folder of the public_html folder. The script should save uploaded files into a folder inside public_html directory(say images). In other words let us say that my file is test.php and the path to it is

/home/user/public_html/test/test.php. 

有一个文件夹

/home/user/public_html/images 

必须保存通过test.php上传的文件.我不知道将在哪里运行test.php文件.例如，它可以位于路径

where files uploaded via test.php have to be saved. I don't know where the test.php file will be run. For example it can be at the path

/home/user/public_html/test/another-dir/test.php

如何在不知道test.php文件在哪里的情况下获取images文件夹的路径?

How do I get the path to the images folder without knowing where the test.php file will be?
