$ _SERVER ['HOME']没有显示正确的值nginx ubuntu

Question

I have a nginx server with php5-fpm on ubuntu 14.

when I echo $_SERVER['HOME'] it return back /var/www

my web files located in /usr/share/nginx/html

obviously it's not my home directory if i type ~/ in the terminal I can get the home directory that is /home/myname

I couldn't find where this information set and why it set wrong.

Answer 1

$_SERVER['HOME'] returns the home path of the current user.

If nginx is running as (for example) www-data, then you'll get the home-directory of www-data.

I guess that you need $_SERVER['DOCUMENT_ROOT'].
