Code to force download files in PHP (solve the problem of garbled Chinese file names under IE)_PHP Tutorial

A problem encountered in the middle is that if the submitted Chinese file name is placed directly in the header, it will become garbled under IE. The solution is to urlencode the file name first and then put it into the header, as follows.

Copy code The code is as follows:

$file_name = urlencode($_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']);
?>

$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 . '"');
}
