#2 Get the menu object

Suppose we have a menu location name: my_menu_location registered with register_nav_menu(). And we created a menu in the admin and attached it to that location. Then:

$locations = get_nav_menu_locations();

if( isset( $locations['my_menu_location'] ) ){

	$items = wp_get_nav_menu_object( $locations['my_menu_location'] );
	print_r( $items );

	/* will output
	stdClass Object
	(
		[term_id] => 693
		[name] => Panel
		[slug] => panel
		[term_group] => 0
		[term_taxonomy_id] => 701
		[taxonomy] => nav_menu
		[description] => 
		[parent] => 0
		[count] => 1
		[filter] => raw
	)
