PHP удалить дубликаты из массива

Question

Мне было интересно, может ли кто-нибудь помочь мне, я пытаюсь найти скрипт, который проверит весь мой массив и при необходимости удалит все дубликаты, а затем выложит массив в том же формате.

Вот пример моего массива (как вы увидите, есть несколько дубликатов):

Array

Answer 1

Вы можете удалить дубликаты из массива, выполнив:

$array = array_values(array_unique($array));

Answer 2

Попробуйте, это работает с большими массивами:

$original = array('one', 'two', 'three', 'four', 'five', 'two', 'four');
$filtered = array();
foreach ($original as $key => $value){
    if(in_array($value, $filtered)){
        continue;
    }
    array_push($filtered, $value);
}

print_r($filtered);

Выходы:

Array
(
    [0] => one
    [1] => two
    [2] => three
    [3] => four
    [4] => five
)

Answer 3

Используйте функцию array_unique.

Вот реализация многомерной функции array_unique.

function super_unique($array)
{
  $result = array_map("unserialize", array_unique(array_map("serialize", $array)));

  foreach ($result as $key => $value)
  {
    if ( is_array($value) )
    {
      $result[$key] = super_unique($value);
    }
  }

  return $result;
}

Не проверено, из комментариев в руководстве по эксплуатации.

Answer 4

прекратите использовать свою собственную функцию разбиения массива, которая вызывает дублирование, и прочитайте справочную страницу php на array_chunk

Answer 5

Мой PHP ржавый, но что-то вроде этого должно работать:

function makeUniqueBidArray(&$array)
{
  $tempArray = array();
  foreach($array as $bidArray) {
    foreach($bidArray as $bid) {
      if (isset($tempArray[$bid->bid]) {
        unset($bid);
      } else {
        $tempArray[$bid->bid] = $bid->name;
      }
    }
  }
}
