多维数组MySQLi-->；PHP-->；JSON-->；海图

我试图从一个充满传感器值的MySQL数据库中创建一个JSON数组。我正在尝试从MySQL结果创建一个多维数组，这样一个查询就可以完成所有任务，从而有望减少服务器负载

我想使用highcharts中的结果来绘制多个传感器节点和多个传感器的结果。我想用时间轴绘制结果

首先，我不确定一个包含我所有数据的大数组是否是正确的方法，或者多个较小的数组是否更好，欢迎对此发表任何评论。我在寻找帮助的是创建一个JSON数组

到目前为止，我得到的是：

<?php
require_once 'db_login.php'; //get login details for the database

$db_server = new mysqli($db_hostname, $db_username, $db_password, $db_database)or die('There was a problem connecting to the database');

$query = "
SELECT sensorID,timeStamp,theDate,theDay,theHour,avgTemp,avgHumidity,avgLight,avgOccupied
FROM
(
  select
    `sensor_id` AS sensorID,
    `value_date` AS timeStamp,
    DAY(`value_date`) AS theDate,
    DAYNAME(`value_date`) AS theDay,
    HOUR(`value_date`) AS theHour, 
    AVG(`value_temp`) AS avgTemp,
    AVG(`value_humidity`) AS avgHumidity,
    AVG(`value_light`) AS avgLight,
    AVG(`value_PIR`) AS avgOccupied
  FROM sensor_value
  WHERE `value_date` >= (NOW() - INTERVAL 7 DAY)
  AND `value_date` < NOW()
  GROUP BY sensorID,theDate,theHour
) s
GROUP BY sensorID,theDate,theHour; 
";

$result = $db_server->prepare($query);
$result->execute();
$result->bind_result($sensorID, $timeStamp, $theDate, $theDay, $theHour, $avgTemp, $avgHumidity, $avgLight, $avgOccupied);
while ($result->fetch()) 
{
//if($theHour<1) $theHour=0.000001;

//    $data[$sensorID][$theDate][$theDay][$theHour] = array(
//      "Temp" => $avgTemp,
//      "Humidity" => $avgHumidity,
//      "Light" => $avgLight,
//      "Occupied" => $avgOccupied
//    );


      $data[]['ID'] = array(
                "SensorID" => $sensorID,
                "DateID" => array(
                  "Date" => $theDate,
                  "Day" => $theDay,
                  "HourID" => array(
                    "Hour" => $theHour,
                    "Results" => array(
                      "Temp" => $avgTemp,
                      "Humidity" => $avgHumidity,
                      "Light" => $avgLight,
                      "Occupied" => $avgOccupied
                    ),
                  ),
                ),
        );

    );

}

header("content-type: application/json");
echo json_encode($data, JSON_PRETTY_PRINT);

$db_server->close();
?>

如何将结果嵌套在同一传感器下，然后嵌套在同一天下

我从以下代码开始：

while ($result->fetch()) 
{
    $data[$sensorID][$theDate][$theDay][$theHour] = array(
      "Temp" => $avgTemp,
      "Humidity" => $avgHumidity,
      "Light" => $avgLight,
      "Occupied" => $avgOccupied
    );
}

有我想要的那种正确的嵌套，但并没有键，所以我发现很难实际使用结果。剪掉上面的代码：

                },
    ......etc....
    ]

我已经尝试添加一个foreach循环来嵌套数据，但无法构造一个合适的函数来工作

有人能帮我创建这个阵列吗？还是我让自己的生活很艰难？我应该转到多个查询吗

你想要什么结构？与列出的第一个输出相同，但我不希望重复传感器ID或重复一天。呃…看起来你已经这样做了。但是如何使用所需的关键帧获得正确的嵌套？每个对象的关键帧不能超过1个“小时”。
