===========================
MongoDB\\Collection::find()
===========================
.. default-domain:: mongodb
.. contents:: On this page
:local:
:backlinks: none
:depth: 1
:class: singlecol
Definition
----------
.. phpmethod:: MongoDB\\Collection::find()
Finds documents matching the query.
.. code-block:: php
function find($filter = [], array $options = []): MongoDB\Driver\Cursor
This method has the following parameters:
.. include:: /includes/apiargs/MongoDBCollection-method-find-param.rst
The ``$options`` parameter supports the following options:
.. include:: /includes/apiargs/MongoDBCollection-method-find-option.rst
Return Values
-------------
A :php:`MongoDB\\Driver\\Cursor <class.mongodb-driver-cursor>` object.
Errors/Exceptions
-----------------
.. include:: /includes/extracts/error-unsupportedexception.rst
.. include:: /includes/extracts/error-invalidargumentexception.rst
.. include:: /includes/extracts/error-driver-runtimeexception.rst
Behavior
--------
.. include:: /includes/extracts/note-bson-comparison.rst
Examples
--------
The following example finds restaurants based on the ``cuisine`` and ``borough``
fields and uses a :manual:`projection
</tutorial/project-fields-from-query-results>` to limit the fields that are
returned. It also limits the results to 5 documents.
.. code-block:: php
$collection = (new MongoDB\Client)->test->restaurants;
$cursor = $collection->find(
[
'cuisine' => 'Italian',
'borough' => 'Manhattan',
],
[
'limit' => 5,
'projection' => [
'name' => 1,
'borough' => 1,
'cuisine' => 1,
],
]
);
foreach ($cursor as $restaurant) {
var_dump($restaurant);
};
The output would then resemble::
