[MongoDB] 使用PHP根据_id字段查询数据

        $filter['_id']=new MongoDB\BSON\ObjectId($params['id']);;
        $options=[];
        $collect='.modelHis';
        $mongoManger = new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017");
        $query = new MongoDB\Driver\Query($filter, $options);
        $cursor = $mongoManger->executeQuery($dbName.$collect, $query);
        if($cursor->isDead()){
            //return [];
        }
        $items=[];
        foreach ($cursor as $document) {
            $document->_id=$document->_id->__toString();
            $items[]=get_object_vars($document);
        }
