Example
-------

.. start-crud-include

The following operation inserts a document into the ``users`` collection in the
``test`` database:

.. code-block:: php

<?php

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

$insertOneResult = $collection->insertOne([
       'username' => 'admin',
       'email' => 'admin@example.com',
       'name' => 'Admin User',
   ]);

printf("Inserted %d document(s)\n", $insertOneResult->getInsertedCount());

var_dump($insertOneResult->getInsertedId());

The output would then resemble::

Inserted 1 document(s)
   object(MongoDB\BSON\ObjectId)#11 (1) {
     ["oid"]=>
     string(24) "579a25921f417dd1e5518141"
   }
