我這個程序可以讓你上傳任何類型的文件並可以直接顯示或下載下來(upload_and_show.php3)：
if($submit)
{
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: no-cache, must-revalidate");
header("content-type:application/octet-stream");
header("content-disposition:inline;filename=$form_data");
header("content-description:php3 generated data");
$fd = fopen($form_data,"r");
while($string = fread($fd,200)){
echo $string;
}
fclose($fd);
}
else { ?>
