php强制下载文件的代码(解决IE下中文文件名乱码问题)

2. $file_name = urlencode($_REQUEST['filename']);
3. header("Pragma: public"); header("Expires: 0");
4. header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
5. header("Content-Type: application/force-download");
6. header('Content-Type: application/vnd.ms-excel; charset=utf-8');
7. header("Content-Transfer-Encoding: binary");
8. header('Content-Disposition: attachment; filename='.$file_name);

解决PHP Header下载文件在IE文件名中文乱码： 一种是是把页面编码改成utf8。 另一种是对中文url进入urlencode编码。

下面来看解决方案的具体实现代码。 1，页面是utf-8编码：

2. $filename = "中文.txt";
3. $ua = $_SERVER["HTTP_USER_AGENT"];
4. $encoded_filename = urlencode($filename);
5. $encoded_filename = str_replace("+", "%20", $encoded_filename);
6. header('Content-Type: application/octet-stream');
7. if (preg_match("/MSIE/", $ua)) {
8. header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');
9. } else if (preg_match("/Firefox/", $ua)) {
10. header('Content-Disposition: attachment; filename*="utf8''' . $filename . '"');
11. } else {
12. header('Content-Disposition: attachment; filename="' . $filename . '"');
13. }

2，将文件名先urlencode一下再放入header。 代码：

2. $file_name = urlencode($_REQUEST['filename']);
3. header("Pragma: public"); header("Expires: 0");
4. header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
5. header("Content-Type: application/force-download"); //加入强制下载的头信息
6. header('Content-Type: application/vnd.ms-excel; charset=utf-8');
7. header("Content-Transfer-Encoding: binary");
8. header('Content-Disposition: attachment; filename='.$file_name);
9. echo stripslashes($_REQUEST['content']);
10. ?>
