//给你个下载文件的代码吧
$file_name = "要下载的文件名";
$file_dir = dirname(__FILE__)."/";
$file = fopen($file_dir . $file_name,"r"); //打开文件
//输入文件标签
header("Content-type: application/octet-stream");
header("Accept-Ranges: bytes");
header("Accept-Length: ".filesize($file_dir . $file_name));
header("Content-Disposition: attachment; filename=" . $file_name);
//输出文件内容
echo fread($file,filesize($file_dir . $file_name));
fclose($file);
