Laravel 3創建文本（CSV）文件

Question

您好，我試圖抓取數據庫中的所有電子郵件，然後將它們輸出到文本（以逗號分隔）的文件中。這是我做了什麼，但不工作：

public function get_textfile() { 

$emails = Staff::get('email'); 

header("Content-type: text/csv"); 
header("Cache-Control: no-store, no-cache"); 
header('Content-Disposition: attachment; filename="filename.txt"'); 

$stream = fopen("php://output", 'w'); 

foreach($emails as $email) { 
fputcsv($stream, $email, ','); 
} 

fclose($outstream);  
} 

return (something)? 

得到這個錯誤：6（網:: ERR_FILE_NOT_FOUND）：文件或目錄無法找到。

這是我的路線：

Route::get('textfile', array('as' => 'textfile','uses' => 'admin@textfile')); 

Answer 1

嘗試file_put_contents($filename, implode(',', Staff::get('email')));

Answer 2

收集所有的數據轉換成字符串，然後輸出這樣說：

$data = ''; 
foreach ($emails as $email) 
{ 
    // If you want 1 email per line 
    $data .= '"'.$email.'"'.PHP_EOL; 

    // If you want all emails on 1 line 
    $data .= '"'.$email.'",'; 
} 

header('Content-type: text/csv'); 
header('Content-Disposition: attachment; filename=My Cool File.csv'); 
header('Pragma: no-cache'); 
header('Expires: 0'); 

echo $data;
