php下载文件代码(兼容ie6浏览器)

2. $filename = "./".$_REQUEST['name']; //具体路径,只要$filename是所要下载文件的完整路径即可
3. if (!is_file($filename)) {//检测文件是否存在.
4. die('下载的文件好像跟TM谁私奔啦!');
5. }
6. $filepath = str_replace('\\', '/', realpath($filename));
7. $filesize = filesize($filepath);
8. $filename = substr(strrchr('/'.$filepath, '/'), 1);
9. $extension = strtolower(substr(strrchr($filepath, '.'), 1));
10. // use this unless you want to find the mime type based on extension,文件后缀格式,不解释.
11. $mime = array('application/octet-stream');
12. header('Content-Type: '.$mime);
13. header('Content-Disposition: attachment; filename="'.$filename.'"');
14. header('Content-Transfer-Encoding: binary');
15. header('Content-Length: '.sprintf('%d', $filesize));
16. header('Expires: 0');
17. // check for IE only headers,坑爹的IE检测,你懂的.
18. if (isset($_SERVER['HTTP_USER_AGENT']) &&((strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false)))
19. {
20. header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
21. header('Pragma: public');
22. } // bbs.it-home.org
23. else

25. header('Pragma: no-cache');
26. }
27. $handle = fopen($filepath, 'rb');
28. fpassthru($handle);
