For the beginners this will help to understand. Use simply the following based on your relative path:

//include file directly from parent directory:
include_once(dirname(__FILE__) . '/../connect.php');

OR

//include file from parent's child directory:
include_once(dirname(__FILE__) . '/../StoredProcedure/connect.php');

//include file from own child directory:
include_once('StoredProcedure/connect.php');

OR

//include sibling files from same directory:
include_once('connect.php');
