To get root directory path of a PHP project:

For PHP >= 5.3.0

use: __DIR__

Note: The directory of the file. If used inside an include, the directory of the included file is returned. This is equivalent to dirname(__FILE__). This directory name does not have a trailing slash unless it is the root directory.

For PHP < 5.3.0

use: dirname(__FILE__) or realpath(dirname(__FILE__))

Or in most common for getting server document root directory where projects resides : 

$_SERVER['DOCUMENT_ROOT'] or filter_input(INPUT_SERVER, 'DOCUMENT_ROOT')

You can put some php file into the root and get: 

$rootPath = dirname(__FILE__)

inside it.
