Examples

.. code-block:: php
   <?php
   $bucket = (new MongoDB\Client)->test->selectGridFSBucket();
   $stream = fopen('php://temp', 'w+b');
   fwrite($stream, "foobar");
   rewind($stream);
   $id = $bucket->uploadFromStream('filename', $stream);
   var_dump($id);
The output would then resemble::
   object(MongoDB\BSON\ObjectId)#3009 (1) {
     ["oid"]=>
     string(24) "5acf81017e21e816e538d883"
   }
