Parameters Description
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. Sort 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 (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 combine (bitwise OR) SORT_STRING or SORT_NATURAL to sort strings without case sensitivity.

The optional second parameter includes additional sorting flags.
