readfile在新页面中打开，而不是在弹出窗口中下载文件

Question

hi i need help i am using the code below from php.net to allow site visitors download documents on my site

<?php

   $file = $_GET['file'];;

   if (file_exists($file)) {
   header('Content-Description: File Transfer');
   header('Content-Type: application/octet-stream');
   header('Content-Disposition: attachment; filename='.basename($file));
   header('Expires: 0');
   header('Cache-Control: must-revalidate');
   header('Pragma: public');
   header('Content-Length: ' . filesize($file));
   ob_clean();
   flush();
   readfile($file);
   exit;
   }
?>

my problem is that instead of the code outputting a dialog box in order for me to save/download the document as outlined here http://www.php.net/manual/en/function.readfile.php the code opens up in a new page showing abnormal data...the code works perfectly on xampp localhost but not on the server

what might be the problem??

Answer 1

The code seems to be perfect. My thoughts is that the configuration of php.ini in the server and the xampp might be different.

My suggestion is to run <?php phpinfo(); ?> in both server and xampp and compare the configuration and match the xampp's configuration in the server.
