// Accessing the primary menu ID $primary_menu_id = $menu_locations[‘primary-menu’];
// Accessing the footer menu ID $footer_menu_id = $menu_locations[‘footer-menu’];
In the above example, the get_nav_menu_locations function is called without any parameters, which retrieves all the registered menu locations. The returned array, $menu_locations, can then be used to access specific menu IDs by referencing their corresponding location slugs.
By utilizing the get_nav_menu_locations function, you can effortlessly retrieve the menu IDs associated with different menu locations in your WordPress theme, allowing you to customize the navigation menus as per your requirements.
