<?php
function downfile()
{
  $filename = realpath ( "resume.html" ); //文件名
  $date = date ( "Ymd-H:i:m" );
  Header( "Content-type:  application/octet-stream " );
  Header( "Accept-Ranges:  bytes " );
Header( "Accept-Length: " . filesize ( $filename ));
  header( "Content-Disposition:  attachment;  filename= {$date}.doc" );
  echo file_get_contents ( $filename );
  readfile( $filename );
}
downfile();
?>

(推薦這種方法,親測可行,其他的沒測試)
