The following example updates all of the documents with the ``borough`` of
``"Queens"`` by setting the ``active`` field to ``true``:
.. code-block:: php
$collection = (new MongoDB\Client)->test->restaurants;
$updateResult = $collection->updateMany(
[ 'borough' => 'Queens' ],
[ '$set' => [ 'active' => 'True' ]]
);
printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
The output would then resemble::
Matched 5656 document(s)
Modified 5656 document(s)
