Using count() will return the number of items passed in the first
parameter. If it's an array, each element is an item. If it's a
string, the string is an item. If it's an object, logically, the
items depend on what is contained in the object. However, at no time
does it return the number of characters within a string --- instead,
as you likely know, you'd use strlen().
