An array is a collection of values of the same type. Each element of the array is identified with an index or a key. Any type that can be used to declare a variable can be used to declare an array, even another array.
Studio supports the following types of arrays:
Indexed arrays are indexed by consecutive positive integers, starting from 0 (zero).
Associative arrays may be indexed by any type, although certain types are better suited for use as indexes.
