解决PHP文件（word/excel）下载 内容打开乱码问题

编码转换不一定有用，一般可以解决文件名乱码问题

iconv(

'utf-8'

,

'gb2312'

,

$filename

);

具体代码如下：

header(

"Pragma: public"

);

header(

"Cache-control: max-age="

.

$expire

);

//header('Cache-Control: no-store, no-cache, must-revalidate');

header(

"Expires: "

.

gmdate

(

"D, d M Y H:i:s"

,time()+

$expire

) .

"GMT"

);

header(

"Last-Modified: "

.

gmdate

(

"D, d M Y H:i:s"

,time()) .

"GMT"

);

header(

"Content-Disposition: attachment; filename="

.

$showname

);

header(

"Content-Length: "

.

$length

);

header(

"Content-type: "

.

$type

);

header(

'Content-Encoding: none'

);

header(

"Content-Transfer-Encoding: binary"

);

//**********************************

ob_clean();

flush

();

//*********************************

readfile(

$filename

);

注意上面的两行代码

ob_clean();

flush

();
