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。
复制代码 代码如下:
<?php
$file_name = urlencode($_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)：

复制代码 代码如下:
$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:

复制代码 代码如下: <?php
$file_name = urlencode($_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"]);
?>
