Hey Sam,

It just depends on whether you want the results to be sorted in Ascending or Descending order. Just remember the the "r" in arsort() stands for "Reverse"... so, it sorts in reverse order.

asort() sorts in Ascending
arsort() sorts in Descending

For example: (2, 6, 1, 7, 4, 3)

asort() will return 1, 2, 3, 4, 6, 7

arsort() wil return 7, 6, 4, 3, 2, 1

Hope that helps! :) :dizzy:
