    I found I had to manually call the __toString method when I was trying to populate an associative array of mongoguid => stringValue:

            $filter = [];
            $options = [];
            $this->propertyMap = [];
            try {
                $query = new \MongoDB\Driver\Query($filter, $options);
                $cursor = $this->mongo->executeQuery('MyDbName.MyColectionName', $query);
            } catch (Exception $e) {
                echo "Mongo Query failure pulling the collection" . PHP_EOL;
                echo($e->getMessage());
                die("aborting");
            }
            foreach ($cursor as $property) {
                //$this->propertyMap[$property->{_id}->__toString()] = $property->name;
                $this->propertyMap[$property->name] = $property->{_id}->__toString();
            }

    You could also do it as $property->{_id} . "" to get the same string result.  Otherwise you end up with an array of MongoDB\BSON\ObjectID objects.
