The first array ($friend) is arranged using integers as the key (the key is the information between the [brackets]) which is handy when using loops. The second array ($age) shows that you can also use a string (text) as the key. As demonstrated the values are called by print in the same way a regular variable would be.
The same principals apply to arrays as variables: they are CaSe SeNsitiVe, they are always defined with a $, and they must start with a letter or an underscore (not a number.)
