创建单个结果数组作为两个查询的响应

我想从两个独立工作的查询或一个可以组合我的两个查询生成单个结果响应。

    $query =" SELECT *
    FROM locationdetails
    WHERE user_id = " . $userid . " AND trip IN (SELECT DISTINCT trip FROM locationdetails
    GROUP BY trip
    HAVING _id = max( _id ))
    ORDER BY trip DESC
    LIMIT 0 , 5";

和第二个查询几乎相同:

$query =" SELECT *
    FROM locationdetails
    WHERE user_id = " . $userid . " AND trip IN (SELECT DISTINCT trip FROM locationdetails)
    GROUP BY trip
    HAVING _id = min( _id )
    ORDER BY trip DESC
    LIMIT 0 , 5";

，但我需要生成一个响应。需要一些紧急帮助。我还通过如下方法生成响应:

    function ExecuteQuery($query) {
    $response = new ApiResult();
    if (mysqli_query($this->con, $query)) {
        $results_array = array();
        $sqlResult = mysqli_query($this->con, $query);
        while ($row = $sqlResult->fetch_assoc()) {
            $results_array[] = $row;
        }
        if ($results_array != null || !empty($results_array)) {
            $response->Message = 'SUCCESSFULL';
            $response->Result = $results_array;
        } else {
            $response->Message = 'SUCCESSFULL';
            //  $response->Result = 'N;
        }
        mysqli_close($this->con);
    } else {
        $response->Message = 'Some Internal problem occurred';
        $response->Error = true;
    }
    return $response;
}
