Add getDuplicates() method into DiffArray utility class

Created on 27 April 2015, over 10 years ago
Updated 11 May 2025, 5 months ago

Recently I needed to figure out duplicate values in arrays and I have found a solution and after a while I needed it again so I thought that maybe this could be a useful function to have in Drupal right away.

/**
   * Returns duplicated entries from the provided array.
   * http://magp.ie/2011/02/02/find-duplicates-in-an-array-with-php/
   *
   * @param $array
   *
   * @return array
   */
  public function getDuplicates(array $array) {
    return array_values(array_unique(array_diff_assoc($array, array_unique($array))));
  }
