How can I specify an incomplete path in php?

Question

PHP

Let's say I'm making a block site, the php language templates are buried in the depths of the site, you need to specify an incomplete path through the include
file of a single entry point has a load of all scripts, but there is a problem, the scripts need a full path, and I need to specify without taking into account the domain / root folder, let's say not so D:/domen.ru/full_version/js/nprogress.js , and like this /full_version/js/nprogress.js

Answer 1

$_SERVER["DOCUMENT_ROOT"]

Answer 2

You need __FILE__ and __DIR__ there
