----------
.. phpmethod:: MongoDB\\ChangeStream::next()
Advances the change stream and attempts to load the next event.
.. code-block:: php
function next(): void
.. note::
Advancing the change stream does not guarantee that there will be a
current event to access. You should still call
:phpmethod:`MongoDB\\ChangeStream::valid()` to check for a current event
at each step of iteration.
