PHP 다운로드 파일 코드(IE6 브라우저와 호환 가능)

$filename = "./".$_REQUEST['name']; //具体路径,只要$filename是所要下载文件的完整路径即可
if (!is_file($filename)) {//检测文件是否存在.
 die('下载的文件好像跟TM谁私奔啦!');
}
$filepath = str_replace('\', '/', realpath($filename));
$filesize = filesize($filepath);
$filename = substr(strrchr('/'.$filepath, '/'), 1);
$extension = strtolower(substr(strrchr($filepath, '.'), 1));
       // use this unless you want to find the mime type based on extension,文件后缀格式,不解释.
$mime = array('application/octet-stream');
header('Content-Type: '.$mime);
header('Content-Disposition: attachment; filename="'.$filename.'"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: '.sprintf('%d', $filesize));
header('Expires: 0');
// check for IE only headers,坑爹的IE检测,你懂的.
if (isset($_SERVER['HTTP_USER_AGENT']) &&((strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false)))
