上传到服务器时损坏的西里尔文件名 [英] Broken Cyrillic file name when uploading to server

问题描述

我有这个PHP功能：

I have this php function:

function upload_file($f,$fn){
switch($f['type']){
case 'image/jpeg':$image = imagecreatefromjpeg($f['tmp_name']);break;
case 'image/png':case 'image/x-png':move_uploaded_file($f['tmp_name'],'../images/pc/'.$fn.'.png');break;
case 'image/pjpeg':$image = imagecreatefromjpeg($f['tmp_name']);break;
echo $f['type'],'<br />';
}
if(!empty($image)) imagejpeg($image,'../images/pc/'.$fn.'.png');
}    

其中$ fn =нова-категория
但是当我将重命名的文件上传到服务器 - 图像名称已损坏，如下所示：$ b $bновакаС，РμРіРѕСЂРёСЏ.png

where $fn = "нова-категория" but when I upload the renamed file to server - the image name is broken and looks like this: РЅРѕРІР°-категория.png

有趣的是如果我试图访问服务器上的图像：site.com/images/pc/нова-категория.png=>我可以看到图像..
你能告诉我是什么刹车图片名称看看正常吗？

The interesting thing is that if I try to visit the image on server: site.com/images/pc/нова-категория.png => I can see the image.. Can you give me an idea what brakes the image name to look normal?

推荐答案

1. 当您使用ftp客户端浏览ftp时，您会看到ANSI编码的名称（单字节编码）。在这种情况下，РЅРѕРІР°-РєР°С，РμРіРѕСЂРёСЏ.png实际上是UTF-8（双字节）编码нова-категория.png

1. When you browse ftp with ftp client you see ANSI-encoded names (single-byte encodings). In this case нова-категория.png is actually UTF-8 (double-byte) encoded нова-категория.png

当您将文件上传到网络服务器时，浏览器会将文件名中的非unicode符号转换为UTF-8（ нова-категория.png成为РЅРѕРІР°Р,Р°С，РμРіРѕСЂРёСЏ.png）

When you upload file to web server, browser convert non unicode symbols in file name to UTF-8 (нова-категория.png becomes нова-категория.png)

当您请求site.com/images/pc/нова-категория.png浏览器再次将非unicode符号转换为UTF-8且服务器实际上寻找РЅРѕРІР°-РєР°С，РμРіРѕСЂРёСЏ.png（采用ASCI编码）。

When you request site.com/images/pc/нова-категория.png browser again convert non unicode symbols to UTF-8 and server actually looks for нова-категория.png (in ASCI-encoding).

因此，如果你想在ftp-client中看到普通名称，你应该将它们转换为你的原生编码

So if you want to see "normal" names in ftp-client, you should convert them to your native encoding

function upload_file($f,$fn){
$fn=iconv("UTF-8","Windows-1251",$fn);
switch($f['type']){
...

但在这种情况下，您的文件URL会出现问题。
要将正确的URL写入ANSI编码的名称，您应该使用此PHP代码：

But in this case you'll have problems with URLs to your files. To write correct URL to ANSI-encoded names you should use this php code:

echo "site.com/images/pc/".rawurlencode("нова-категория.txt");

您应该处理文件名的方式取决于您对该文件的使用。
但我不建议你转换它们。如果你有问题，我认为它不是破碎的名字。

The way you should handle file names is depends on your use of that files. But I don't recommend you to convert them. If you have problem, I thinks its not in "broken" names.
