PHP 8.0: Class MongoDB\Driver\Cursor must implement interface Traversable as part of either Iterator or IteratorAggregate

ISSUE TYPE

• Question

SUMMARY

When trying to compile MongoDB for PHP 8.0 it seems to work somehow. However, when then running PHP I get the following startup error:

PHP Fatal error:  Class MongoDB\Driver\Cursor must implement interface Traversable as part of either Iterator or IteratorAggregate in Unknown on line 0

Does anyone know how to fix this for PHP 8.0?

Goal

Re-enable mongodb extension for PHP 8.0 without errors.

Update

Upstream issue: mongodb/mongo-php-driver#1161

Refer to this issue, maybe it is caused by adminer??
Query Result Object should implement Countable Interface #742

@vulcangz thanks for the link. Unfortunately this is not it. It is only present in PHP 8.0 and during startup. For instance if I do a php -v on the command the fatal will already be thrown.
