Error While Renaming An Extracted Zip File To Other Languages In PHP

Question

I use PHP ZipArchive class to extract a .zip file, It works fine for English, but cause problems in my local language (THAI).

I use icov('utf-8','windows-874',$zip->getNameIndex($i)) to convert utf-8 to THAI. It works for folder's/file's name, but doesn't work for extracted .zip file and cause this error :

iconv(): Detected an illegal character in input string

Can anyone please tell me what the problem is here?

My PHP code

$file = iconv('utf-8', 'windows-874', $_GET['File']);
$path = iconv('utf-8', 'windows-874', $_GET['Path']);

$zip = new ZipArchive;
if ($zip->open($file) === TRUE) {
    // convert to Thai language
    for($i = 0; $i < $zip->numFiles; $i++) {
        $name = $zip->getNameIndex($i);
        //echo iconv("charset zip file", "windows-874", $name);
        //$zip->extractTo($path,$name); -> this problem
    }
    $zip->close();
    echo json_encode('unZip!!!');
} else {
    echo json_encode('Failed');
}

After I extract the zipped file, The file's name is not the one I set for it.

This is name i try to set :

Here is my zipped file :

https://www.dropbox.com/s/9f4j04lkvsyuy63/test.zip?dl=0

UPDATE
I tried unzipping the file in windows XP, it works fine there but not in windows 7.

Nobody can tell unless you show what the string actually contains. (ZIP files aren't actually renowned for Unicode support. Most tools just use local charsets asis.) — mario, Jul 05 '15 at 15:02
Where is the code you use for actually extracting the content? Could you upload a minimal example of a zip file that gives the error somewhere (after adding the code you use to extract its contents)? — MatsLindh, Jul 05 '15 at 16:09
but it is not better to work the "THAI" with `utf8` anyway? What is the need to convert it to `windows-874`? — Protomen, Jul 05 '15 at 16:15
My directory is thai language and I use $zip->open($file) is Fail but I convert to windows-874 is work for me — Veerapat Boonvanich, Jul 05 '15 at 16:20
You have not provided enough information, most likely this is not a direct problem with the language, it sounds like your file is not a valid zip, this happens all the time in php because of an extra bit in the zip binary, and things like that. Are you downloading via web from a server? Run the following command on linux: zip -T filename.zip and tell us the output. — Neo, Jul 06 '15 at 20:55
I stumbled onto a project that fixes just many encoding issues regarding encoded names of files. I think [this](https://github.com/julp/ImprovedZipArchive) might help. — fsacer, Jul 07 '15 at 14:44
Sorry, I'am very busy and I change file name and directory to english. Thank you very much for help — Veerapat Boonvanich, Aug 31 '15 at 14:55

You probably should try mb_detect_encoding() for help with this - see the code below. You may need to expand on this code if you also have a problem with its path. Just use a loop if you need to do that.

$file = iconv('utf-8', 'windows-874', $_GET['File']);
$path = iconv('utf-8', 'windows-874', $_GET['Path']);

$zip = new ZipArchive;
if ($zip->open($file) === TRUE) {
    // convert to Thai language
    for($i = 0; $i < $zip->numFiles; $i++) {
        $name = $zip->getNameIndex($i);
        $order = mb_detect_order();
        $encoding = mb_detect_encoding($name, $order, true);
        if (FALSE === $encoding) {
             throw new UnexpectedValueException(
                sprintf(
                    'Unable to detect input encoding with mb_detect_encoding, order was: %s'
                , print_r($order, true)
                )
             );
        } else {
            $encoding = mb_detect_encoding($name);
            $stringUtf8 = iconv($encoding, 'UTF-8//IGNORE', $name);
            $zip->extractTo($path,$stringUtf8);
        }  
    }
    $zip->close();
    echo json_encode('unZip!!!');
} else {
    echo json_encode('Failed');
}

Thank you for your code, but doesn't work and I change to english. It's easier than Thai file name. Thank you very much — Veerapat Boonvanich, Aug 31 '15 at 14:47
