Php json_编码的格式化数组

我已经寻找了几天，试图拼凑出我的解决方案，但仍在挣扎。我正在努力使用一些php，并将其转换为我想要的json编码格式，以便使用knockout.js

我有一个db，看起来像这样：

| id | name       | value                  |
| 1  | taskName   | First Task             |
| 1  | taskDetail | Enter your first task  |
| 1  | taskList   | Very Important         |
| 2  | taskName   | Second Task            |
| 2  | taskDetail | Enter your second task |
| 2  | taskList   | Important              |

[
  {
    "id": "1",
    "taskName": "First Task",
    "taskDetail": "Enter your first task",
    "taskList": "Very Important"
  },
  {
    "id": "2",
    "taskName": "Second Task",
    "taskDetail": "Enter your second task",
    "taskList": "Important"
  }
]

while ($row = mysql_fetch_assoc($result))
{           
    if (!isset($results[$row['id']])) $results[$row['id']] = array();
    $results[$row['id']][$row['name']] = $row['value'] );
}

我试图用json_encode将此响应发送到我的站点，如下所示：

| id | name       | value                  |
| 1  | taskName   | First Task             |
| 1  | taskDetail | Enter your first task  |
| 1  | taskList   | Very Important         |
| 2  | taskName   | Second Task            |
| 2  | taskDetail | Enter your second task |
| 2  | taskList   | Important              |

[
  {
    "id": "1",
    "taskName": "First Task",
    "taskDetail": "Enter your first task",
    "taskList": "Very Important"
  },
  {
    "id": "2",
    "taskName": "Second Task",
    "taskDetail": "Enter your second task",
    "taskList": "Important"
  }
]

while ($row = mysql_fetch_assoc($result))
{           
    if (!isset($results[$row['id']])) $results[$row['id']] = array();
    $results[$row['id']][$row['name']] = $row['value'] );
}

以下是我到目前为止的情况：

$user = 1;

$task_sql = "
    SELECT *
    FROM `li_id`
    INNER JOIN `li_details`
    ON li_id.id = li_details.id
    WHERE li_id.user = '" . $user . "'";


$result = mysql_query($task_sql, $con);
$results = array();

while ($row = mysql_fetch_assoc($result)) {
    $results[] = array($row['name'] => $row['value']);
}

echo json_encode($results);

答复：

[
  {
    "taskName": "First Task"
  },
  {
    "taskDetail": "Enter first task in application."
  },
  {
    "taskList": "Important"
  },
  {
    "taskName": "Second Task"
  },
  {
    "taskDetail": "Enter second task in application."
  },
  {
    "taskList": "Very Important"
  }
]

问题是，我无法找出如何按id分组到单独的数组中。我试过好几种方法，但都不走运。任何指向其他线程的提示或方向都将非常棒。谢谢

像这样的东西怎么样：

| id | name       | value                  |
| 1  | taskName   | First Task             |
| 1  | taskDetail | Enter your first task  |
| 1  | taskList   | Very Important         |
| 2  | taskName   | Second Task            |
| 2  | taskDetail | Enter your second task |
| 2  | taskList   | Important              |

[
  {
    "id": "1",
    "taskName": "First Task",
    "taskDetail": "Enter your first task",
    "taskList": "Very Important"
  },
  {
    "id": "2",
    "taskName": "Second Task",
    "taskDetail": "Enter your second task",
    "taskList": "Important"
  }
]

while ($row = mysql_fetch_assoc($result))
{           
    if (!isset($results[$row['id']])) $results[$row['id']] = array();
    $results[$row['id']][$row['name']] = $row['value'] );
}

然后在对其进行json_编码后，所有字段都嵌套在其id中

如果表结构（数据库）不正确，是否将一个条目分成3？为何ID应该是自动递增的。为什么表结构是这样的？创建一个具有id、taskName和taskDetail属性的PHP类。在获取循环中创建此类的实例数组。序列化。我有另一个表，在添加新项时自动递增。此表中的id与这些项目相关，因此我知道每个项目应用哪些属性。格式与我发布的略有不同，但这仍然是我所需的魅力所在。非常感谢。以下是供其他人查看的结果：{“1”：{“taskName”：“First Task”，“taskDetail”：“在应用程序中输入第一个Task.”，“taskList”：“重要”}，“2”：{“taskName”：“Second Task”，“taskDetail”：“在应用程序中输入第二个Task.”，“taskList”：“非常重要”}
