hebrew - PHP ZipArchive non-English filenames return funky filenames within archive

Question

This code works properly to make the ZIP file with the wanted files, except the filenames in the archive, which are not in English (in this case they are Hebrew), have weird characters instead of the proper hebrew letters.

<?php
$filesfordown = $_POST['GEMin'];
    if(empty($filesfordown)) 
    {
        echo "No files were seleceted for download.";
    } 
    else 
    {
$zip_name = "RMW." . time() . ".zip";
$zip = new ZipArchive;
$zip->open($zip_name, ZipArchive::CREATE);
foreach ($filesfordown as $filefordown) {
  $zip->addFile($filefordown);
}
$zip->close(); }

header('Content-Type: application/zip');
header("Content-disposition: attachment; filename='$zip_name'");
header('Content-Length: ' . filesize($zip_name));
readfile($zip_name);

ob_flush;
?>

I did some searching around, it seems that iconv, setlocalte, or mb_convert_encoding might help, but whatever I tried didn't work.

Any ideas?

P.S. As a side question, is there a way to not keep directory structure in the zip?

ETA: An example of the $_post may be www.domain.com/path/????_01.mp3

Yay! Fixed!

First the code, then an explanation:

<?php 
setlocale(LC_ALL, 'he_IL.UTF-8');
$filesfordown = $_POST['GEMin'];
    if(empty($filesfordown)) 
    {
        echo "?? ?????.. ??? ???";
    } 
    else 
    {
$zip_name = "RMW" . time() . ".zip";
$zip = new ZipArchive;
$zip->open($zip_name, ZipArchive::CREATE);
echo "???? ?? ??????...";
foreach ($filesfordown as $filefordown) {
  $zip->addFile($filefordown, iconv("UTF-8","CP862",basename($filefordown)));
}
$zip->close(); 

3 things needed to be changed.

1. Verify that the actual php file is UTF-8.
2. setlocale() needs to include the .UTF-8 at the end.
3. ZipArchive does not handle UTF-8 correctly. Must use CP. Hebrew was CP862. Therefore, use extra option $localname for addFile, and its basically iconv("UTF-8","CODE_PAGE_REF",$localname)
