Definition
----------

.. phpmethod:: MongoDB\\Database::__get()

Select a collection within the database.

.. code-block:: php

function __get($collectionName): MongoDB\Collection

This method has the following parameters:

.. include:: /includes/apiargs/MongoDBDatabase-method-get-param.rst

Return Values
-------------

A :phpclass:`MongoDB\\Collection` object.

Behavior
--------

The selected collection inherits options such as read preference and type
mapping from the :phpclass:`Database <MongoDB\\Database>` object. If you wish to
override any options, use the :phpmethod:`MongoDB\\Database::selectCollection`
method.

.. note::

To select collections whose names contain special characters, such as
   ``.``, use complex syntax, as in ``$database->{'that.database'}``.

Alternatively, :phpmethod:`MongoDB\\Database::selectCollection` supports
   selecting collections whose names contain special characters.

Examples
--------

The following example selects the ``users`` and ``system.profile``
collections from the ``test`` database:

.. code-block:: php

<?php

$db = (new MongoDB\Client)->test;

$users = $db->users;
   $systemProfile = $db->{'system.profile'};
