$zip = new ZipArchive;
$zipFile = 'path/to/your/zip/file.zip';

if ($zip->open($zipFile, ZipArchive::CREATE) === TRUE) {
    $zip->close();
    echo 'Empty ZIP file created successfully.';
} else {
    echo 'Failed to create empty ZIP file.';
}

$zip = new ZipArchive;
$zipFile = 'path/to/your/zip/file.zip';
$comment = 'Your comment here';

if ($zip->open($zipFile) === TRUE) {
    $zip->setArchiveComment($comment);
    $zip->close();
    echo 'Comment added to the ZIP file successfully.';
} else {
    echo 'Failed to open ZIP file.';
}

$zipFile = 'path/to/your/zip/file.zip';

header('Content-Type: application/zip');
