You can get this information via PHP without calling out to JSP. To get the location of the current request, use
$_SERVER['REQUEST_URI'];
This will return the complete URI, including the script name. If you want only the directory structure and not the trailing script name, you can use trim()
to remove the excess. For convenience, note that the script name is stored here:
$_SERVER['SCRIPT_NAME'];
