$_SERVER[“SCRIPT_URI”] not working? alternative?

Question

This is odd, but for some reason the $_SERVER[\"SCRIPT_URI\"] will not return the domain name when I am in child/sub-pages but will only work on the main page.

Answer 1

Depending on what you want, I'd use one of the following:

1. $_SERVER['PHP_SELF'] for the script file location
2. $_SERVER['SERVER_NAME'] for the host name

From the php docs

EDIT: Maybe PHP_SELF isn't the best. See comments.
