 * Hi,
    I am writing a customer theme, and want to use a global variable in the 
   function.php. It looks like the global variable is loosing it value which is 
   set in a filter function.
 * How can I achieve that the value, which is set in the filter function is available
   in the function.php?
 * Here is the code of my function.php showing the issue I have.
 *     ```
       <?php
   
       $myGlobalVar;
       print_r($myGlobalVar);
   
       add_theme_support('menus');
   
       //register menue locations
       function register_my_menus() {
           global $helperClass;
           register_nav_menus(
                   array('top-menu' => __('Top Menu'),
                       'left-menu' => __('Left Menu'))
           );
       }
   
       add_action('init', 'register_my_menus');
   
       // add hook
       add_filter('wp_nav_menu_objects', 'my_wp_nav_menu_objects_sub_menu', 10, 2);
   
       // filter_hook function to react on sub_menu flag
       function my_wp_nav_menu_objects_sub_menu($sorted_menu_items, $args) {
           global $myGlobalVar;
   
           $myGlobalVar = array("this is a global var", "This as well");
   
           return $sorted_menu_items;
       }
   
       ?>
       ```
   
 * thanks to all of you for helping me here.
