Get the Folder in which the index.php script is Php

Question

I am using AltoRouter to match routes for my php app. Apparently even if index.php is called, if the app is not in the domain root, you have to set $router->setBasePath("/path/to/script");

I need a function that collect the subfolder(if app is in subfolder).Eg if path is /dir and someone calls www.domain.com/dir, i can know its /dir and call $router->setBasePath("/dir");

You can use this rule in your .htaccess:

RewriteEngine On

RewriteCond $0#%{REQUEST_URI} ^([^#]*)#(.*)\1$
RewriteRule ^.*$ - [E=BASE:%2]

This will set `${ENV:BASE}" to whatever sub-directory this .htaccess is residing in.

Then inside PHP you can use:

$_SERVER["BASE"]

which will be set to /dir/ if .htaccess is in /dir1/.
