从PHP变量下载/执行数据

Question

I am trying to download PHP buffer output at the client's end. I am not interested in writing the output content to a file on the server and then allowing the download. I have checked my variable output by printing it on the browser. Since the buffer is supposed to be downloaded at the client's end as a file, where should I specify the file name?

<?php
  $file=$_POST['file'];
  header('Content-Description: File Transfer');
  header('Content-Type: application/x-java-jnlp-file');  
  ob_clean();
  flush();
  readfile($file);
 ?>

You'll need the "Content-Disposition" header:

header( 'Content-Disposition: attachment; filename="downloaded.pdf"' );
