How use left join in foreach?

[misterkonst]

foreach ($model_params as $join_key => $join_value) {
            if ($join_value->relationship !== null) {
                $query->leftJoin(
                    $join_value->relationship,
                    $join_key,
                    $join_value->foreign_key,
                );
            }
        }
