Examples
--------
The following example updates one document with the ``restaurant_id`` of
``"40356151"`` by setting the ``name`` field to ``"Brunos on Astoria"``:
.. code-block:: php
   $collection = (new MongoDB\Client)->test->restaurants;
   $updateResult = $collection->updateOne(
       [ 'restaurant_id' => '40356151' ],
       [ '$set' => [ 'name' => 'Brunos on Astoria' ]]
   );
   printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
   printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
The output would then resemble::
   Matched 1 document(s)
   Modified 1 document(s)
