MongoDB\ChangeStream::next()

Definition

MongoDB\ChangeStream::next()

Advances the change stream and attempts to load the next event.

function next(): void

Note

Advancing the change stream does not guarantee that there will be a current event to access. You should still call

MongoDB\ChangeStream::valid() to check for a current event at each step of iteration.
