Gaufrette提供了一个文件系统的抽象层的PHP5库。它使得以相同方式操控本地文件，FTP服务器，亚马逊S3等等。它允许你开发程序时，不用了解未来你将怎么访问你的文件。
示例代码：
<?phpuse Gaufrette\Filesystem;use Gaufrette\Adapter\Ftp as FtpAdapter;use Gaufrette\Adapter\Local as LocalAdapter;use Gaufrette\Adapter\Cache as CacheAdapter;// Locale Cache-Directory (e.g. '%kernel.root_dir%/cache/%kernel.environment%/filesystem') with create = true$local = new LocalAdapter($cacheDirectory, true);// FTP Adapter with a defined root-path$ftp = new FtpAdapter($path, $host, $username, $password, $port);// Cached Adapter with 3600 seconds time to live$cachedFtp = new CacheAdapter($ftp, $local, 3600);$filesystem = new Filesystem($cachedFtp);
