Find the path to 'project_a' relative to script in 'project_b_2':

$path = realpath( dirname( __FILE __ ) . '/../../project_a/' );

Find the path to 'project_a' relative to the webroot:

$path = $_SERVER['DOCUMENT_ROOT'] . '/Project/project_a/';

Using $_SERVER['DOCUMENT_ROOT'] will always reference to where the root is in your defined site/vhost etc.
So using something like this should work: 

fopen($_SERVER['DOCUMENT_ROOT'].'/projectA/subfileB.html');

You should be able to go up in the directory tree :

#when you are in project/project_b/project_b_2
$dir = "../../project_a";

That is the way I usually follow, although you can use 

$_SERVER["SITE_HTMLROOT"]

which should take you to the root of the website
