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) {
