wp_get_nav_menu_itemsの戻り値
このサイトの、「ヘッダーメニュー」というか、「ヘッダーナビ」というか、「グローバルナビ」というか（どれも同じモノ？？）、
それの詳細を表示させてます。
以下は、メニュー名を「ヘッダーメニュー」にして、「wp_get_nav_menu_items()」を呼び出したときの戻り値です。
リストを出して見た感じでは、
「$item->db_id」と「$item->ID」は、メニュー構造の（？）ＩＤで、その親を示すのが「$item->item_paremt」。
「$item->object_id」は、該当する投稿や固定ファイルのＩＤで、その親を示すのが「$item->post_parent」
になってるみたいな気がします。（あえて曖昧な表現）
wp_get_nav_menu_items
「ヘッダーメニュー」の内容を取得
