Question

我有一个类属性，我定义了一个关联数组

private $jsonArray = array('Friends' => array());

我试图将数组中的每个朋友都放入数组中 [已接受] =测试

 $query = "SELECT Username, Status 
          FROM Users 
          INNER JOIN Friends 
          ON Users.idUser = Friends.idFriend 
          WHERE Friends.idUser = ? ";

    // Prepares and excutes the query
    if($stmt = $this->connection->prepare($query))
    {

        $stmt->bind_param('s', $this->id);
        $stmt->execute();
        $stmt->bind_result($friend, $status); 

        for ($i=0; $stmt->fetch(); $i++) 
        { 

           $this->jsonArray['Friends'][$status] = $friend;
        } 

    }

这是为其工作的朋友定义键的正确方法，但是当我json编码它的dict而不再是数组时

{
    "response": {
        "status":"Success",
        "friends": [
            "Andrew",
            "Jake",
            "Matt",
            "Phil",
            "Colton"
        ],
        "groups": [
            {
                "GroupId": "12",
                "GroupMembers": [
                    "Andrew",
                    "Matt",
                    "Colton"
                ],
                "GroupName": “Group1”
            },
            {
                "GroupId": "12",
                "GroupMembers": [
                    "Phil",
                    "Matt",
                    "Colton"
                ],
                "GroupName": "Room 201"
            }
        ]
    }
}

有了这个，你每$friend总会有一个[$status] - 如果需要，那就没关系。但从外表来看，你会更喜欢这样的事情

for ($i=0; $stmt->fetch(); $i++)  {
    $this->jsonArray['Friends'][$status][] = $friend;
}

现在，$friend内有[$status]个数组。

...
Friends: {
    "Accepted": ["friend1", "friend2", ...]
}
...

或者这个

for ($i=0; $stmt->fetch(); $i++)  {
    $this->jsonArray['Friends'][] = $friend;
}

既然你知道他们的$status - 为什么要使用呢？

...
Friends: ["friend1", "friend2", ...]
...
