如何过滤进入CSV文件的数据？

我试图使用数据库中的值生成一个CSV文件并强制下载它。它工作正常，除了文件正在从服务器获取（不相关的）错误消息并将它们包括在CSV文件中。我如何防止这种情况发生？如何过滤进入CSV文件的数据？

这里是我的功能：

public function export($coupons_ids) { 
     $coupons_ids = explode(',', (urldecode($coupons_ids))); 

     $result = $this->cart_coupons->get_where_in('id',array_filter($coupons_ids, 'strlen')); 

     header('Content-Type: text/csv; charset=utf-8'); 
     header('Content-Disposition: attachment; filename=coupons.csv'); 

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

     fputcsv($output, array('id', 'name', 'start_date', 'end_date', 'promo', 'usage_limit')); 

     foreach ($result as $row) 
     { 
      $id = $row->id; 
      $name = $row->name; 
      $start_date = $row->start_date; 
      $end_date = $row->end_date; 
      $usage_limit = $row->usage_limit; 

      $active = ''; 
      switch($row->active) 
      { 
      case 0: 
       $active = 'YES'; 
       break; 
      case 1: 
       $active = 'NO'; 
       break; 
      } 

      $promo = '$0'; 
      switch($row->promo_type) 
      { 
      case 0: 
       $promo = '$' . $row->promo_value; 
       break; 
      case 1: 
       $promo = $row->promo_value . '%'; 
       break; 
      } 

      $data = array('id' => $id, 'name' => $name, 'start_date' => $start_date, 'end_date' => $end_date, 'promo' => $promo, 'usage_limit' => $usage_limit); 
      fputcsv($output, $data); 
     } 

     fclose($output); 

    }

输出是：

77,CC00012,"2013-04-16 00:00:00","2013-04-23 00:00:00",$100,1

我知道这个错误是，它是完全无关的和无关的代码的功能。任何帮助表示赞赏。

明显的是修复导致警告的代码。快速/肮脏的解决方案是关闭display_errors，以便这些警告从不首先得到输出。稍微不太明显：fopen（）在真实文件上，然后在生成csv后读取文件（）该文件。 PHP不会将警告写入该句柄。 – 2013-04-09 19:02:23

把error_reporting(0);放在脚本的开头，以便快速解决问题

解决方案真的很脏。每个人都必须把它放在他们的脚本中，以阻止信息泄露。但真正的解决方案更多。但是+1 – 2013-04-09 19:08:13
