$myArray[0] 
$myArray[1] 

In a similar manner, array elements can be accessed counting backward, from the end. The last element is available using the -1 index, and the penultimate element using the -2 index, for example:

$myArray[-1] 
$myArray[-2] 

Ranges of elements may be selected either going forward (starting from 0) or going backward (starting with -1):

$myArray[2..4] 
$myArray[-1..-5] 

More than one range can be selected in a single statement:

$myArray[0..2 + 6..8 + -1]
