Example
-------

The following example drops the ``users`` collection in the ``test`` database:

.. code-block:: php

   <?php

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

   $result = $db->dropCollection('users');

   var_dump($result);

The output would then resemble::

   object(MongoDB\Model\BSONDocument)#8 (1) {
     ["storage":"ArrayObject":private]=>
     array(3) {
       ["ns"]=>
       string(10) "test.users"
       ["nIndexesWas"]=>
       int(1)
       ["ok"]=>
       float(1)
     }
   }
