Synopsis:
$getitem(

Technical:
These functions are used to fetch data held in the given array. The $getitem(
) function retrieves data based on its item number in the array (counting
from zero, the order in which the data was entered). The $igetitem( )
function retrieves it based on its index number (counting from zero, in a sorted
order). These functions only affect arrays created with $setitem( ).

These functions are used to get an item in an array. The applications for these
function should be obvious. The $igetitem( ) function, in particular,
is useful for showing an array's contents in alphabetical order.

array item data, or empty string if array or item is not found
