 * I have a php module included through my wordpress functions.php file
    and it 
   is stored in my theme directory however i do not have access to wordpress core
   functions or other functions stored in functions.php in my themes root directory.
 * A basic overview of my site structure is
 *     ```
       functions.php
       /functions/locator/webzone.php << Included in functions php
       ```
   
 * and webzone includes
 *     ```
       include_once('config.php');
       include_once($_SERVER['DOCUMENT_ROOT'].$GLOBALS['app_base_path'].'include/more_functions/db_functions.php');
       include_once($_SERVER['DOCUMENT_ROOT'].$GLOBALS['app_base_path'].'include/more_functions/Forms.php');
       include_once($_SERVER['DOCUMENT_ROOT'].$GLOBALS['app_base_path'].'include/db/db_class.php');
       include_once($_SERVER['DOCUMENT_ROOT'].$GLOBALS['app_base_path'].'include/library/gmap/Gmap_class.php');
       ```
   
 * and so on…
 * **Question**
    Why am i not able to access wordpress functions and theme functions
   if all these files are included from the themes functions.php
