Questions about getting the site root

Domain Access: http://www.123.com
IP access: Http://123.123.123.123/hei

Ask how not to work with the domain name or IP access can get the correct root directory. $_server[' http_host '] with domain name can, but with IP is wrong

Speak your specific needs to make further analysis.

I am now doing an upload file function, upload to the set directory, I want to no matter where I put this feature file directory, can upload files to the same directory

__dir__
DirName ($_server[' script_filename ')
Getcwd

The upload directory is the relative path to the directory where the uploaded program files are received.

Use a relative path.
