In PHP, if the file name to be downloaded is called Chinese, the file title is garbled.

In this case, you need to encode the title, that is, urlencode, and then put the header. then the problem is solved.

$ Filename = urlencode (""); header ("Content-disposition: attachment; filename=$filename.xls ");

According to the Internet, in RFC2231 definition, the Content-Disposition of multi-language encoding should be defined as follows:

The code is as follows:

Content-Disposition: attachment; filename * = "utf8'%e6%b5%8b%e8%af%95.html"

That is:

The filename value is divided into three sections by single quotes, which are character set (utf8), Language (null), and URL code file names.

Therefore, url encoding should be performed on the file name. using php's urlencode can be easily completed.

$ Ua = _ SERVER ["HTTP_USER_AGENT"]; $ filename = "Chinese file name .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: attachment; filename = "'. $ encoded_filename. '"');} else if (preg_match ("/Firefox/", $ ua) {header ('content-Disposition: attachment; filename * = "utf8 \'\''. $ filename. '"');} else {header ('content-Disposition: attachment; filename = "'. $ filename. '"');}
