Working with Japanese filenames in PHP 5.3 and Windows Vista?

Question

I'm currently trying to write a simple script that looks in a folder, and returns a list of all the file names in an RSS feed. However I've hit a major wall... Whenever I try to read filenames with Japanese characters in them, it shows them as ?'s. I've tried the solutions mentioned here: http://stackoverflow.com/questions/482342/php-readdir-problem-with-japanese-language-file-name - however they do not work for some reason, even with:

header('Content-Type: text/html; charset=UTF-8');
setlocale(LC_ALL, 'en_US.UTF8');
mb_internal_encoding("UTF-8");

At the top (Exporting as plain text until I can sort this out).

What can I do? I need this to work and I don't have much time.

Answer 1

This is not possible. It is a limitation of PHP itself. PHP does not use the wide WIN32 API calls, so you're limited by the codepage. UTF-8 (65001) is not valid for this purpose.

If you set a breakpoint at readdir_r() in win32\readdir.c, you'll see that FindNextFile already returns a filename with question marks in place of the characters you want, so there's nothing you can do about it, apart from patching PHP itself.

Answer 2

You can do it in PHP. Write a small C program to read directories and call that program from PHP.

Answer 3

This displays Japanese filenames correctly on a Windows server

if ($handle = opendir($this->dir)) {
    while (false !== ($file = readdir($handle))){
        $name = mb_convert_encoding($file, "UTF-8", "SJIS-win" );
        echo "$name<br>";
    }
    closedir($handle);
}
