MongoDB\\Database::__get()
==========================
.. default-domain:: mongodb
.. contents:: On this page
:local:
:backlinks: none
:depth: 1
:class: singlecol
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'};
