<?php

$fileStr=$_POST['txtFile'];
$fileStrArray=split('[/\]',$fileStr);

$file_dir =substr($fileStr,0,strlen($fileStr)-strlen($file_name));
$encoded_filename = rawurlencode($file_name);
if (!file_exists($file_dir . $file_name)) {
echo "can't find file!";
exit();
}else{
$file = fopen($file_dir . $file_name,"r");
header("Content-type: application/octet-stream");
header("Accept-Ranges: bytes");
header("Accept-Length: ".filesize($file_dir . $file_name));
header("Content-Disposition: attachment; filename=\"" . $encoded_filename . "\";");
echo fread($file,filesize($file_dir . $file_name));
fclose($file);
exit();
}
?>

请问，怎么改才能让要下载的文件另存为时，文件名中的中文显示正常?

$ua = $_SERVER["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: attachment; filename="' . $encoded_filename . '"');
}
else if (preg_match("/Firefox/", $ua))
{
header('Content-Disposition: attachment; filename*="utf8\'\'' . $filename . '"');
}
else
{
header('Content-Disposition: attachment; filename="' . $filename . '"');
}
print 'ABC';
exit;

我试过这种方法，但IE下还是乱码，记得程序要保存UTF-8格式.
