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:

header("Expires:

header("Content-Type:

header("Content-Transfer-Encoding:

header('Content-Disposition:
attachment;
filename='.$file_name);
echo
stripslashes($_REQUEST['content']);
?>
