php中强制下载文件的代码（解决了IE下中文文件名乱码问题）

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。

复制蔽或代码

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(我清烂的页面是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

将文宏正伍件名先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'])

?>

解决PHP下载文件名中的中文乱码问题

<?php

$ua = $_SERVER["春山HTTP_USER_AGENT"]

$filename = "中文 文件名.txt"

$encoded_filename = urlencode($filename)

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

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

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

header('Content-Disposition: attachmentfilename="' . $encoded_filename . '"肢槐')

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

header('Content-Disposition: attachmentfilename*="utf8\'\'扒饥中' . $filename . '"')

} else {

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

}

?>
