多維數組CSV

-1

我得到這個數組：多維數組CSV

array (
    'cat' => 
    array (
    0 => 
    array (
     'name' => 'Sales',

我想所有的數據轉換爲csv文件。問題是，我似乎無法得到它的工作，因爲所有的子陣列。

這是我曾嘗試：

header("Content-Disposition: attachment; filename=\"demo.xls\""); 
header("Content-Type: application/vnd.ms-excel;"); 
header("Pragma: no-cache"); 
header("Expires: 0"); 
$out = fopen("php://output", 'w'); 
foreach ($result as $data) 
{ 
    $finalResult = []; 
    array_walk_recursive($data, function($item) use (&$result) { 
      $finalResult[] = $item; 
     }); 
    fputcsv($out, $finalResult,"\t"); 
} 
fclose($out);

這就是我想要的CSV文件看起來像在Excel中：

任何想法，我怎麼能得到這個工作？任何幫助都感激不盡。

可否請你更新的問題，以顯示線條來你所期望的CSV輸出的？您想如何將多維數據摺疊成二維？ – mkaatman

另外，如果向我們展示'var_export（）'而不是'print_r（）'，我們可以獲得一個數組表示，我們可以複製/粘貼並輕鬆測試我們的答案。我們這些打擾測試我們的答案是 – RiggsFolly

增加了一個例子@mkaatman –

這可能是做你想要什麼

$out = fopen("tst.csv", 'w'); 
$finalResult = []; 
foreach ($result['cat'] as $sales){ 
    foreach ($sales['subs'] as $occ => $stuff){ 
     foreach ($stuff['videos'] as $video) { 
      $line = [$sales['name'], $stuff['key'], $video['vid_url'], $video['nice_name'] ]; 
      //$finalResult[] = $a; 
      fputcsv($out, $line); 
     } 
    } 
} 
//print_r($finalResult); 
fclose($out);

將會產生
