php刪除數組中的重複項

我想知道是否有人可以幫助我，我試圖找到一個腳本，將檢查我的整個數組，並刪除任何重複如果需要，然後吐出陣列在相同的格式。php刪除數組中的重複項

這裏是我的陣列的例子（你會看到有一些重複）：

你有很多嵌套數組。你的意思是重複的？例如。第一個子數組包含一個ID爲「57」的對象。這是否意味着，這個對象應該在第二個（和所有進一步的）子陣列中被刪除？ – 2010-05-18 21:35:17

*可能重複*：http://stackoverflow.com/questions/307674/how-to-remove-duplicate-values-from-a-multi-dimensional-array-in-php – 2010-05-18 21:38:07

是的，這就是我之後..我知道它是多維的，但是如果有任何來自任何子陣列的任何東西的重複，它應該被刪除:) – SoulieBaby 2010-05-18 21:38:10

使用array_unique功能。

這是一個多維array_unique函數的實現。

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; 
}

未經測試，來自功能手冊中的註釋。

我試過了，但它仍然顯示重複的 – SoulieBaby 2010-05-18 21:40:13

+1，但是這似乎非常熟悉（http://stackoverflow.com/questions/1247950/how-to-remove-duplicated-2 -dimension-array-in-php/1248189＃1248189）... xP – 2010-05-18 21:40:16

您需要將對象轉換爲數組並使用'array_merge'。 – 2010-05-18 21:42:38

您可以通過執行從數組中刪除重複項：

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

這是否適用於多維數組？我不這麼認爲... – 2010-05-18 21:37:17

我的PHP的生疏，但這樣的事情應該工作：使用

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; 
     } 
    } 
    } 
}

停止，導致重複自己的陣列劃分功能和閱讀array_chunk

php手冊頁試試這個，它與大型陣列：

$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);

輸出：

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