And, of course, the previous line is available at $arr[$x - 1]

(unless we're talking $x == 0)

    Well, if you consider arrays to be circular, if $x == 0, then $arr[$x - 1] is the last element. Which would be just right. Unfortunally, it doesn't work the way. $arr[$#arr + 1] isn't the same as $arr[0].
