我在stackoveflow上找到了一些关于如何压缩特定文件的代码，但是特定文件夹又如何呢？

Folder/
  index.html
  picture.jpg
  important.txt

在中My Folder，有文件。压缩后My Folder，我还想删除文件夹的全部内容，除了important.txt。

我需要你的帮助。谢谢。

// Get real path for our folder
$rootPath = realpath('folder-to-zip');
// Initialize archive object
$zip = new ZipArchive();
$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);
// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($rootPath),
    RecursiveIteratorIterator::LEAVES_ONLY
);
foreach ($files as $name => $file)
{
    // Skip directories (they would be added automatically)
    if (!$file->isDir())
    {
        // Get real and relative path for current file
        $filePath = $file->getRealPath();
        $relativePath = substr($filePath, strlen($rootPath) + 1);
        // Add current file to archive
        $zip->addFile($filePath, $relativePath);
    }
}
// Zip archive will be created only after closing object
$zip->close();

        // delete it later cause ZipArchive create archive only after calling close function and ZipArchive lock files until archive created)
        if ($file->getFilename() != 'important.txt')
        {
            $filesToDelete[] = $filePath;
        }
    }
}
// Zip archive will be created only after closing object
$zip->close();
// Delete all files from "delete list"
foreach ($filesToDelete as $file)
{
    unlink($file);
}
