Array Problem

I have an array:
menu_links = ['?page=home_content', ['?page=steaks_about', '?page=steaks_about', '?page=steaks_recipe', '?page=steaks_sauce'], ['?page=potatoes_about', '?page=potatoes_about', '?page=potatoes_recipe'], ['?page=asparagus_about', '?page=asparagus_about', '?page=asparagus_recipe'], '?page=feedback'];


Now, the way it looks to me, there are array's inside this array... how would one pull out seperate pieces of the inner ones? The way this array is set up is not something I have the ability to change, so I have to work with it this way. Any thoughts?

 

To make it easier for you to see, let me use a different content of the array and format slightly differently:

menu = [
   'rice',
   ['spaghetti', 'fettuccine', 'penne'],
   'noodles',
   ['water', 'orange juice', 'coke']
];

Code (markup):

The contents of the array are:
menu[0] => 'rice'
menu[1] => the array ['spaghetti', 'fettuccine', 'penne']
menu[1][0] => 'spaghetti'
menu[1][1] => 'fettuccine'
menu[1][2] => 'penne'
menu[2] => 'noodles'
menu[3] => the array ['water', 'orange juice', 'coke']
menu[3][0] => 'water'
menu[3][1] => 'orange juice'
menu[3][2] => 'coke'

 

Oh! Thanks. I had no idea you could add the latter thing onto it. Thanks!
