 * me again
    my issue has been resolved..for those who are looking to run wordpress
   function from external php files..they have to write this 3 lines in the beginning
   of their php file
 *     ```
       define('WP_USE_THEMES', false);
       require_once (dirname (dirname (__FILE__)) . '/websitefoldername/wp-blog-header.php');
       require_once (dirname (dirname (__FILE__)) . '/websitefoldername/wp-includes/registration.php');
       ```
   
 * NOTE
    Please change websitefoldername to your site folder name after this they
   can run any wordpress function.. I am creating users using this technique
