Does foreach() work for non-numerical array keys?

Question

I was wondering if foreach() works when the array looks like this:

• arr_name[eggs] = something
• arr_name[pencil] = something else

Answer 1

Yes, foreach supports any kind of key. In your case, $key will be a string, 'eggs' and 'pencil' respectively for each item. In fact, foreach was intended for use with arrays that have non-numerical keys which you can't easily iterate using for.
