array Required. Specifies the array to be sorted.
sortingtype

Optional. Specifies how to sort the elements/items of the array. Possible values:

  • 0 = SORT_REGULAR - Default. Arrange each item in the standard order (Standard ASCII, do not change type).
  • 1 = SORT_NUMERIC - Treat each item as a number.
  • 2 = SORT_STRING - Treat each item as a string.
  • 3 = SORT_LOCALE_STRING - Treat each item as a string, based on the current locale setting (can be changed via setlocale()).
  • 4 = SORT_NATURAL - Treat each item as a string, using a natural sorting similar to natsort().
  • 5 = SORT_FLAG_CASE - Can be combined (bitwise OR) with SORT_STRING or SORT_NATURAL to sort strings without case sensitivity.

Description

The arsort() function sorts an array in reverse order while maintaining the index relationship. It is mainly used to sort combined arrays where the order of units is very important.

The optional second parameter includes additional sorting identifiers.
