============================= MongoDB\\GridFS\\Bucket Class ============================= .. default-domain:: mongodb .. contents:: On this page :local: :backlinks: none :depth: 1 :class: singlecol Definition ---------- .. phpclass:: MongoDB\\GridFS\\Bucket :manual:`GridFS </core/gridfs>` is a specification for storing and retrieving files in MongoDB. GridFS uses two collections to store files. One collection stores the file chunks (e.g. ``fs.chunks``), and the other stores file metadata (e.g. ``fs.files``). The :phpclass:`MongoDB\\GridFS\\Bucket` class provides an interface around these collections for working with the files as PHP :php:`Streams <stream>`. You can construct a GridFS bucket using the driver's :php:`Manager <class.mongodb-driver-manager>` class, or select a bucket from the library's :phpclass:`MongoDB\\Database` class via the :phpmethod:`selectGridFSBucket() <MongoDB\\Database::selectGridFSBucket>` method.
