As with other programming languages, in PHP also sorting arrays and their values have a high importance.

An array can be sorted in ascending or descending order and with numerous functions that use numerical or alphabetical approach.

Syntax for basic array sorting

$arrays = ("value1", "value2", "value3");
sort ($arrays); // ascending order
rsort ($arrays); // descending order

Following functions may be used in array sorting:

  • sort() - sorting ascending
  • rsort() - sorting descending
  • asort() - sorting ascending of associative array
  • ksort() - sorting ascending of associative array according to key
  • arsort() - sorting descending of associative array
  • krsort() - sorting descending of associative array according to key
