Synopsis:
$getitem(<array> <item#>)
$igetitem(<array> <index#>)
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().
Practical:
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.
Returns:
array item data, or empty string if array or item is not found
