中间遇到一个问题是提交的中文文件名直接放到header里在IE下会变成乱码，解决方法是将文件名先urlencode一下再放入header，如下。

$file_name = urlencode($_REQUEST['filename']);

header("Pragma: public"); header("Expires: 0");

header("Cache-Control: must-revalidate, post-check=0, pre-check=0");

header("Content-Type: application/force-download");

header('Content-Type: application/vnd.ms-excel; charset=utf-8');

header("Content-Transfer-Encoding: binary");

header('Content-Disposition: attachment; filename='.$file_name);

echo stripslashes($_REQUEST['content']);

?>

解决PHP Header下载文件在IE文件名中文乱码有两种常见的，一种是是把页面编码改成utf8，另一种是对中文url进入urlencode编码就可以解决了。

解决方案一(我的页面是utf-8编码)：

$filename = "中文.txt";

$ua = $_SERVER["HTTP_USER_AGENT"];

$encoded_filename = urlencode($filename);

$encoded_filename = str_replace("+", "%20", $encoded_filename);

header('Content-Type: application/octet-stream');

if (preg_match("/MSIE/", $ua)) {

header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');

} else if (preg_match("/Firefox/", $ua)) {

header('Content-Disposition: attachment; filename*="utf8''' . $filename . '"');

} else {

header('Content-Disposition: attachment; filename="' . $filename . '"');

}

解决方法二

将文件名先urlencode一下再放入header，如下。

代码如下:

$file_name = urlencode($_REQUEST['filename']);

header("Pragma: public"); header("Expires: 0");

header("Cache-Control: must-revalidate, post-check=0, pre-check=0");

header("Content-Type: application/force-download");

header('Content-Type: application/vnd.ms-excel; charset=utf-8');

header("Content-Transfer-Encoding: binary");

header('Content-Disposition: attachment; filename='.$file_name);

echo stripslashes($_REQUEST['content']);

?>
