刪除具有相同值的數組中的項目

-1

請參閱我的下列數組，我需要能夠刪除具有相同值的項目（例如，主要，次要等）是否有對現有數組執行此操作的方法通過PHP或更容易做到這一點之前項目插入到數組中？刪除具有相同值的數組中的項目

我見過array_unique功能，但不知道如果我可以使用它看起來是因爲它是一個多維數組？

Array 
(
    [0] => SelectAttributeTypeOption Object 
     (
      [error] => 
      [ID] => 19 
      [value] => Primary 
      [th] => TextHelper Object 
       (
       ) 

      [displayOrder] => 0 
      [usageCount] => 
     ) 

    [1] => SelectAttributeTypeOption Object 
     (
      [error] =>

這要看數據的來源，以及它是如何添加到陣列中。如果它來自DB，你很可能改變你的查詢這樣做.. – Naruto 2014-10-17 09:12:32

爲什麼不從SQL語句解決這個問題，你需要添加的是'GROUP BY值' – 2014-10-17 09:12:36

在array_filter功能請看：

array_filter($array, function($elem) use ($value) { 
    return $elem['value'] !== $value; 
});

希望它能幫助。

試試這個：

$new = array_reduce(
    $old, 
    function ($result, $item) { 
     if (!in_array($item, $result)) { 
      $result[] = $item; 
     } 
     return $result; 
    } 
);

但如果這些對象是牽強從數據庫，你最好的過濾你的結果與你有GROUP BY id或任何唯一的記錄標識符事先設定，爲Finciuc的Sergiu建議。

我希望這有助於

foreach($array as $row) { 
    if(!isset($output[$row['value']])) { 
     $output[$row['value']] = $row; 
    } 
} 

//reset array keys if you want //$output = array_values($output)
