A string is series of characters, therefore, a character is the same as a byte. That is, there are exactly 256 different characters possible.

An array in PHP is actually an ordered map. A map is a type that associates values to keys. This type is optimized for several different uses; it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more. As array values can be other arrays, trees and multidimensional arrays are also possible.

Note: The quiz covers only PHP 4 - not PHP 5
