PHP – multi-sort of associative array in PHP

January 6th, 2013 by Laeeq | No comments

This is a complete multi-sort example of associative array in PHP. We have first sorted an associative array by values in descending order then sorted an associative array by keys in ascending order.

  1. <?php
  2. $asso_arr = Array
  3. (
  4. ‘banana’ => 2,
  5. ‘cherry’ => 1,
  6. ‘orange’ => 3,
  7. ‘grapefruit’ => 1,
  8. ‘apple’ => 1
  9. );
  10. $values = array_values($asso_arr);
  11. $keys = array_keys($asso_arr);
  12. //first sort by values desc, then sort by keys asc
  13. array_multisort($values, SORT_DESC, $keys, SORT_ASC, $asso_arr);
  14. print_r($asso_arr);
  15. ?>

 

Output:

Array
(
[orange] => 3
[banana] => 2
[apple] => 1
[cherry] => 1
[grapefruit] => 1
)
