try:
<?

error_reporting('0');
if(!isset($File))$File = "temp.txt";$Path = "./upfiles/";
$filestail=strrchr($File,".");
$namestr = str_replace($filestail,"",$File);
$strs = split("-",$namestr);
$Path .= "D".$strs[2]."/";
header("Content-type: application/x-gzip");

readfile($Path.$File);?>

Answer 2

function download()
{
$upload_dir= "../".$_GET['path'];
$upload_file  = $_GET['filename'];
$fp = fopen($upload_dir.$upload_file,"r"); 
Header("Content-type: application/octet-stream");
Header("Accept-Ranges: bytes");
Header("Accept-Length: ".filesize($upload_dir.$upload_file));
Header("Content-Disposition: attachment; filename=" . $upload_file);

fclose($fp);
}

Answer 3

不能用改名的方式，更不能右键另存...
我对php接触没有几天。。 sandyuk(冰の沙隆) 和bonniewater(陪你去看海) 两位大侠能否详细解释该怎么做，该放到哪里，我的下载链接该怎么写阿？

Answer 4

而且我写header时会包错
Warning: Cannot add header information - headers already sent by (output started at c:\Program Files\Apache Group\Apache\htdocs\hcycom\host\grid.php:7) in c:\Program Files\Apache Group\Apache\htdocs\hcycom\host\grid.php on line 8

Answer 5

<a href=download.php?filename=a.txt&path=c:/>下载</a>
你把这个函数写到一个文件download.php中
download.php
<?php
function download()
{
$upload_dir= "../".$_GET['path'];
$upload_file  = $_GET['filename'];
$fp = fopen($upload_dir.$upload_file,"r"); 
Header("Content-type: application/octet-stream");
Header("Accept-Ranges: bytes");
Header("Accept-Length: ".filesize($upload_dir.$upload_file));
Header("Content-Disposition: attachment; filename=" . $upload_file);
echo fread($fp,filesize($upload_dir . $upload_file));
fclose($fp);
}
download();
?>
