header("Cache-Control: no_cache");
header("Pragma: no-cache");
header("Content-Type: text/html; charset=utf-8");
require 'class/fileDown.class.php';
$name=urldecode($_REQUEST["name"]);
//echo $name;
down_file($name,"/MianXiangDuixiang/down/");

fileDown.class.php页面如下:
header("Expires: -1");
header("Cache-Control: no_cache");
header("Pragma: no-cache");
header("Content-Type: text/html; charset=utf-8");
function down_file($file_name,$file_sub_dir)
{
$file_name=iconv("gb2312","GBK",$file_name);
$file_path = $_SERVER['DOCUMENT_ROOT'].$file_sub_dir.$file_name;
if(!file_exists($file_path))
{
echo"文件不存在";
return ;
}
$fp = fopen($file_path,"r");
$file_size = filesize($file_path);
header("Content-type: application/octet-stream");
header("Accept-Ranges: bytes");
header("Accept-Length: $file_size");
header("Content-Disposition: attachment; filename=".$file_name);
$buffer = 1024;
$file_count = 0;
while(!feof($fp) && ($file_size-$file_count>0))
{
$file_data = fread($fp,$buffer);
$file_count+=$buffer;
echo $file_data;
}
fclose($fp);
}
?>
