Definition

.. phpmethod:: MongoDB\\ChangeStream::getCursorId()

   Returns the change stream cursor's ID.

   .. code-block:: php

      function getCursorId(): MongoDB\Driver\CursorId

Return Values
-------------

A :php:`MongoDB\\Driver\\CursorId <class.mongodb-driver-cursorid>` object.

Examples
--------

This example reports the cursor ID for a change stream.

.. code-block:: php

   <?php

   $uri = 'mongodb://rs1.example.com,rs2.example.com/?replicaSet=myReplicaSet';

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

   $changeStream = $collection->watch();

   var_dump($changeStream->getCursorId());

The output would then resemble::

   object(MongoDB\Driver\CursorId)#5 (1) {
     ["id"]=>
     int(8462642181784669708)
   }
