Where to store a common variable

[eluser]Jaketoolson[/eluser]
I'm working on the same... I have sub menus and therefore my arrays wouldn't contain as much information as yours.

Code:

$nav = array(
  'home' => array(//sub-menu
      'about', 'contact'
      ),
  'stuff' => array(//submenu
      'more', 'pages'
      ),
  );

And then the value would also serve as the id and link... i created a nav cfg file and autoload it.
