使用 MySQL 中的键创建 JSON 数组数组来唱 JSON 对象

Question

我试图在一个 JSON 对象的循环中创建一个数组数组，但它返回的是两个对象。如果我用一个键删除数组周围的数组，它可以工作，但我需要这个键。

这是我正在寻找的格式：

$shop = array( "1408842145690" => array( id => "1408842145690", 
                                 code => "1",
                                 title => "zdfdsf",
                                 date => "2014-08-01",
                                 description => "fghgf"
                                ),
        "1408840099517" => array( id => "1408840099517", 
                                 code => "1",
                                 title => "test",
                                 date => "2014-08-01",
                                 description => "this is a test"
                                )
         );echo json_encode($shop);

这是我正在使用的代码

$query = " SELECT * FROM todolist ";
if ($result = mysqli_query($mysqli,$query)) {
    while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
        $tasks = array(
                       $row['task_id'] => array( 'id' => $row['task_id'],
                                           'code' => $row['task_statusbox'],
                                           'title' => $row['task_title'],
                                           'date' => $row['task_date'],
                                           'description' => $row['task_description']
                                          )             
                    );  
        $alltasks[] = $tasks;
    }
    echo json_encode($alltasks);
    /* free result set */
    $result->close();  
}

这是我得到的结果：

{"1408842145690":{"id":"1408842145690","code":"1","title":"zdfdsf","date":"2014-08-01 00:00:00","description":"fghgf"}},{"1408840099517":{"id":"1408840099517","code":"1","title":"test","date":"2014-08-01 00:00:00","description":"this is a test"}}

这就是我要找的结果

{"1408842145690":{"id":"1408842145690","code":"1","title":"zdfdsf","date":"2014-08-01","description":"fghgf"},"1408840099517":{"id":"1408840099517","code":"1","title":"test","date":"2014-08-01","description":"this is a test"}}

将 while 循环的内容替换为以下内容：

$tasks = array('id' => $row['task_id'],
             'code' => $row['task_statusbox'],
             'title' => $row['task_title'],
             'date' => $row['task_date'],
             'description' => $row['task_description']
         );            
$alltasks[$row['task_id']] = $tasks;

编辑：我测试了上述内容，它确实有效。这是完整的替换代码...尝试复制/粘贴。

$query = " SELECT * FROM todolist ";
if ($result = mysqli_query($mysqli,$query)) {
    while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
        $tasks = array('id' => $row['task_id'],
            'code' => $row['task_statusbox'],
            'title' => $row['task_title'],
            'date' => $row['task_date'],
            'description' => $row['task_description']
        );            
        $alltasks[$row['task_id']] = $tasks;
    }
    echo json_encode($alltasks);
    /* free result set */
    $result->close();  
}
