The assignment to $query is dead and can be removed.

        $query = $this->buildWhereQuery($where);
        $query = $this->buildWhereRawQuery($whereRaw, $query);
        $whereInQuery = $this->buildWhereInQuery($whereIn);
        if (count($whereInQuery)) {
            $query = array_merge($query, $whereInQuery);

It seems like $query can also be of type null; however, parameter $array1 of array_merge() does only seem to accept array, maybe add an additional type check?
