Array中相同的PHP

我有一個這樣的數組：Array中相同的PHP

Array 
(
    [0] => Array 
     (
      [fileid] => 7 
      [remarks] => 
      [filename] => whomovedmycheese - Copy.pdf 
      [type] => application/pdf 
      [size] => 500624 
     ) 

    [1] => Array 
     (
      [fileid] => 7 
      [remarks] => 
      [filename] => whomovedmycheese.pdf 
      [type] => application/pdf 
      [size] => 500624 
     ) 

    [2] => Array 
     (
      [fileid] => 8 
      [remarks] => 
      [filename] => whomovedmycheese - Copy.pdf 
      [type] => application/pdf 
      [size] => 500624 
     ) 

    [3] => Array 
     (
      [fileid] => 8 
      [remarks] => 
      [filename] => whomovedmycheese.pdf 
      [type] => application/pdf 
      [size] => 500624 
     ) 

)

這是我的陣列我想刪除重複的。我試圖刪除使用下面的代碼重複。

$input4 = array_map("unserialize", array_unique(array_map("serialize", $basicinfo3))); 
$new_data3 = array_values($input4);

但是結果仍然與起始數組相同。在上面的代碼$basicinfo具有上述數組的值。我想要做的是刪除重複的數組，所以它將如下所示。

Array 
    (
     [0] => Array 
      (
       [fileid] => 7 
       [remarks] => 
       [filename] => whomovedmycheese - Copy.pdf 
       [type] => application/pdf 
       [size] => 500624 
      ) 

     [1] => Array 
      (
       [fileid] => 7 
       [remarks] => 
       [filename] => whomovedmycheese.pdf 
       [type] => application/pdf 
       [size] => 500624 
      ) 
    )

UPDATE

你的問題不清楚，能否請您用例子來解釋？ – Prakash

不能使用以上，因爲這考慮到了獨特的全陣列批，因爲你已經可以看到該功能，一些fileid已經不同與相同的文件名。如果您需要基於filename，那麼正常的循環就足夠了。

在您的示例輸出中，似乎首先發現的是優先級，然後簡單的isset應該沒問題。

$input4 = array(); 
foreach($basicinfo3 as $values) { 
    if(!isset($input4[$values['filename']])) { 
     $input4[$values['filename']] = $values; // if doesn't exist yet, push it 
    } 
} 

$input4 = array_values($input4); // simple reindex

Sample Output

只是一個問題，我想在fileid上的建議是數據庫中的條目的id增量id是比文件名檢查更好的參數？ –

@HogRider好吧，我知道的大多數操作系統都不允許重複的文件名，所以是的，你需要使用文件名而不是遞增的ID – Ghost

什麼是操作系統抱歉還沒有遇到該術語 –

$newArray = array_unique($oldArray, SORT_REGULAR);

您可以使用普通的PHP數組來實現這一目標。

<?php 
$data = Array 
(
    0 => Array 
     (
      "fileid" => 7, 
      "remarks" => '', 
      "filename" => "whomovedmycheese - Copy.pdf", 
      "type" => "application/pdf", 
      "size" => "500624", 
     ), 

    1 => Array 
     (
      "fileid"=> 7, 
      "remarks" => '', 
      "filename"=> "whomovedmycheese.pdf", 
      "type"=> "application/pdf", 
      "size" => "500624", 
     ), 

    2 => Array 
     (
      "fileid"=> 8, 
      "remarks"=> '', 
      "filename"=> "whomovedmycheese - Copy.pdf", 
      "type"=> "application/pdf", 
      "size" => "500624", 
     ), 

    3 => Array 
     (
      "fileid"=> 8, 
      "remarks"=> '', 
      "filename"=> "whomovedmycheese.pdf", 
      "type"=> "application/pdf", 
      "size" => "500624", 
     ) 
); 

$newArray = array(); 
foreach ($data as $file) 
{ 
    $newArray[$file['filename']] = $file; 
} 
echo "<pre>"; 
print_r($newArray); 
?>
