How to use xdebug in sublime text 3 without hosting or domain?

Question

Sublime Text

Apache server sites are here

/var/www/html

Here is a link to this folder in the browser

127.0.0.1

What if I need to debug this file http://127.0.0.1/namespaces/( /var/www/html)
That is, what do I need to write in the file untitled.sublime-project?
I can’t figure it out myself (
PS Tell me, do I need to somehow configure xdebug, if I have already specified these settings

[xdebug]
zend_extension = /absolute/path/to/your/xdebug-extension.so
;zend_extension = "C:\Program Files (x86)\PHP\ext\php_xdebug.dll"
xdebug.remote_enable = 1
xdebug.remote_host = " 127.0.0.1"
xdebug.remote_port = 9000
xdebug.remote_handler = "dbgp"
xdebug.remote_mode = req
xdebug.remote_connect_back = 1

(I do not notice any hint of his work)
