.. phpclass:: MongoDB\\Collection

   Provides methods for common operations on collections and documents,
   including CRUD operations and index management.
   
   You can construct collections directly using the PHP extension's
   ``Manager`` class, select a collection from the |php-library|'s
   :phpclass:`MongoDB\\Client` or :phpclass:`MongoDB\\Database`
   classes, or create a collection from an existing collection using the
   :phpmethod:`withOptions <MongoDB\\Collection::withOptions>` clone method.
    
   :phpclass:`MongoDB\\Collection` supports the :php:`readConcern
   <mongodb-driver-readconcern>`, :php:`readPreference
   <mongodb-driver-readpreference>`, :php:`typeMap
   <mongodb.persistence.php#mongodb.persistence.typemaps>`, and
   :php:`writeConcern <mongodb-driver-writeconcern>` options.
   If you omit an option, the collection inherits the value from the
   Manager constructor argument or the Database object used to select
   the collection.

   Operations within the ``Collection`` class
   inherit the Collection's options.
   
   The :phpmethod:`MongoDB\\Collection::aggregate` method (when not
   using a cursor), :phpmethod:`MongoDB\\Collection::distinct`, and
   :manual:`findAndModify </reference/command/findAndModify>` helpers do not
   support a ``typeMap`` option due to a driver limitation.
   :phpmethod:`MongoDB\\Collection::aggregate`,
   :phpmethod:`MongoDB\\Collection::distinct`,
   :phpmethod:`MongoDB\\Collection::findOneAndReplace`,
   :phpmethod:`MongoDB\\Collection::findOneAndUpdate`, and
   :phpmethod:`MongoDB\\Collection::findOneAndDelete`
   return BSON documents as `stdClass` objects and arrays as arrays.
