1.4.3和PHP

Question

我目前創建和輸出一個CSV如下保存CSV：

header('Content-Type: text/csv; charset=utf-8'); 
header('Content-Disposition: attachment; filename=file.csv'); 
header("Cache-Control: no-store, no-cache"); 

$df = fopen('php://output', 'w'); 
fprintf($df, chr(0xEF).chr(0xBB).chr(0xBF)); 
foreach ($csvLines as $csvLine) { 
    fputcsv($df, $csvLine); 
} 
exit; 

不過，我想不僅輸出，而且這個文件保存到磁盤。我怎樣才能將$df寫入文件？

注意改善我的生成CSV建議，歡迎:)

Answer 1

最簡單的答案是寫入文件，而不是php://output，和然後直接發送文件到使用readfile()

header('Content-Type: text/csv; charset=utf-8'); 
header('Content-Disposition: attachment; filename=file.csv'); 
header("Cache-Control: no-store, no-cache"); 

$df = fopen('/path/to/where/you/want/the/file/on/disk.csv', 'w'); 
fprintf($df, chr(0xEF).chr(0xBB).chr(0xBF)); 
foreach ($csvLines as $csvLine) { 
    fputcsv($df, $csvLine); 
} 
readfile('/path/to/where/you/want/the/file/on/disk.csv'); 
exit; 

Answer 2

簡單地寫兩個文件指針：

$out = fopen('php://output', 'w'); 
$file = fopen('somefile.csv'); 

fprintf($out, chr(0xEF).chr(0xBB).chr(0xBF)); 
fprintf($file, chr(0xEF).chr(0xBB).chr(0xBF)); 

foreach ($csvLines as $csvLine) { 
    fputcsv($out, $csvLine); 
    fputcsv($file, $csvLine); 
} 

exit;
