在重複數組鍵/值中插入默認值

Question

我有一個以這種方式構建的csv文件。它給我pagesviews數量按小時

"00","ARTICLE 1",100 
"00","ARTICLE 2",50 
"00","ARTICLE 3",30 
"01","ARTICLE 1",40 
"01","ARTICLE 2",100 
"01","ARTICLE 4",200 
"02","ARTICLE 1",30 
"02","ARTICLE 2",40 
"02","ARTICLE 3",30 
"03","ARTICLE 5",30 

我導入CSV在我的PHP代碼，我在mutidimensional陣列插入內容。當我的var_dump我的陣列，這是我所得到的

Array 
(
[00] => Array 
    (
     [ARTICLE 1] => 100 
     [ARTICLE 2] => 50 
     [ARTICLE 3] => 30 
    ) 

[01] => Array 
    (
     [ARTICLE 1] => 40 
     [ARTICLE 2] => 100 
     [ARTICLE 4] => 200 
    ) 

[02] => Array 
    (
     [ARTICLE 1] => 30 
     [ARTICLE 2] => 40 
     [ARTICLE 3] => 30 
    ) 

[03] => Array 
    (
     [ARTICLE 5] => 30 
    ) 

) 

所以我的問題是「第4條」只在「01」看，但我想它出現在鍵「00」，「02」， 「03」的默認值爲0.對於僅出現在「03」鍵的「第5條」也是如此。我想它出現在鍵「00」，「01」，「02」，「03」，「04」

末，我想我的數組appeear這樣

Array 
(
[00] => Array 
    (
     [ARTICLE 1] => 100 
     [ARTICLE 2] => 50 
     [ARTICLE 3] => 30 
     [ARTICLE 4] => 0 
     [ARTICLE 5] => 0 
    ) 

[01] => Array 
    (
     [ARTICLE 1] => 40 
     [ARTICLE 2] => 100 
     [ARTICLE 3] => 0 
     [ARTICLE 4] => 200 
     [ARTICLE 5] => 0 
    ) 

[02] => Array 
    (
     [ARTICLE 1] => 30 
     [ARTICLE 2] => 40 
     [ARTICLE 3] => 30 
     [ARTICLE 4] => 0 
     [ARTICLE 5] => 0 
    ) 

[03] => Array 
    (
     [ARTICLE 1] => 0 
     [ARTICLE 2] => 0 
     [ARTICLE 3] => 0 
     [ARTICLE 4] => 0 
     [ARTICLE 5] => 30 
    ) 

) 

我試圖做這樣的事情，但它不工作

foreach ($orig as $item) { 
$new[] = $item; 
$new[] = $item; 

} 

可有一個人請幫助？

UPDATE

我想是這樣的

foreach ($articles as $article) 
{ 
$pageviews2[$article] = $pageviews; 
} 

其中$ pageviews2包含我的CSV文件的內容和數組文章這樣

$articles = Array("00", "01", "02", "03","04","05"); 

及以下的結構當我var_dump $ pageviews2數組時獲得結果

Array 
(
[00] => Array 
    (
     [00] => Array 
      (
       [ARTICLE 1] => 100 
       [ARTICLE 2] => 50 
       [ARTICLE 3] => 30 
      ) 

     [01] => Array 
      (
       [ARTICLE 1] => 40 
       [ARTICLE 2] => 100 
       [ARTICLE 4] => 200 
      ) 

     [02] => Array 
      (
       [ARTICLE 1] => 30 
       [ARTICLE 2] => 40 
       [ARTICLE 3] => 30 
      ) 

     [03] => Array 
      (
       [ARTICLE 5] => 30 
      ) 

    ) 

[01] => Array 
    (
     [00] => Array 
      (
       [ARTICLE 1] => 100 
       [ARTICLE 2] => 50 
       [ARTICLE 3] => 30 
      ) 

     [01] => Array 
      (
       [ARTICLE 1] => 40 
       [ARTICLE 2] => 100 
       [ARTICLE 4] => 200 
      ) 

     [02] => Array 
      (
       [ARTICLE 1] => 30 
       [ARTICLE 2] => 40 
       [ARTICLE 3] => 30 
      ) 

     [03] => Array 
      (
       [ARTICLE 5] => 30 
      ) 

    )

我已經處理過這種情況的方式正如你所提到的那樣，用一組已知值預填充每個「外部」元素。這是基於這樣一種假設，即您確切知道在數組的第二維中需要多少個元素，並且事先知道第一個元素中將包含多少個元素。下面是一些代碼來演示：

$pageviews = array(); 
$articles = Array("00", "01", "02", "03"); 

$prepopulated = Array (
    "Article 1" => 0, 
    "Article 2" => 0, 
    "Article 3" => 0, 
    "Article 4" => 0, 
    "Article 5" => 0 
); 

然後，您可以導入CSV之前創建一個骨架陣列：

foreach ($articles as $article) { 
    $pageviews[$article] = $prepopulated; 
} 

然後，當你從CSV，所有導入的數據，你正在做的您剛纔創建的骨架陣列中，在覆蓋默認值：

if (($handle = fopen("pageviews.csv", "r")) !== FALSE) { 
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { 
     $pageviews[$data[0]][$data[1]] = $data[2]; 
    } 
    fclose($handle); 
}
