Angular 应用程序的 php JSON 数据结构

Question

我正在尝试将 mysql 响应格式化为对象数组，以便 Angular 可以轻松遍历数据。

mysql 结果:

[{
    "FIAccountsID": "99",
    "AccountName": "",
    "AccountCustomName": "Brothers",
    "AccountNumber": "99-123123123",
    "AccountTypeName": "IRA",
    "FinancialInstName": "Testes",
    "FinancialInstID": "9",
    "UserID": "1",
    "ofxStatusCode": "500",
    "UserAccountID": "09128-vc-12",
    "FirstName": "Someones",

{
    "FIAccountsID": "103",
    "AccountName": "",

    "UserAccountID": "09128-vc-12",
    "FirstName": "Someones",
    "LastName": "Name",
    "Status": "2"
}......

这里是 PHP:

while($row = mysqli_fetch_assoc($result))   
{ 

  $uid = $row['UserID'];
  $name = $row['FirstName'].' '.$row['LastName'];
  $fiid = $row['FinancialInstID'];
  $fi = $row['FinancialInstName'];
  $acctID = $row['FIAccountsID'];


  $rows[$uid]['name'] = $name;
  $rows[$uid]['uid'] = $uid;
  $rows[$uid]['fi'][$fiid]['name'] = $fi;
  $rows[$uid]['fi'][$fiid]['acct'][$acctID]['name'] = $row['AccountCustomName'];

}

print json_encode($rows); 

这就是我得到的:

{
"1": {
    "name": "Some Name",
    "uid": "1",
    "fi": {
        "9": {
            "name": "Testes",
            "accts": {
                "99": {
                    "name": "name 1"
                },
                "100": {
                    "name": "name 2"
                },
                "103": {
                    "name": "name 3"
                }
            }
        }
    }
},
"2": {
    "name": "Another Name",
    "uid": "2",
    "fi": {
        "7": {
            "name": "Trevor's Brokerage House",
            "accts": {
                "1": {
                    "name": "Sally's 401k Account"
                },
                "2": {
                    "name": "retirement"
                },
                "3": {
                    "name": "Some other account"
..........

期望的结果:

    "users": [
        {
            "name": "Some Name",
            "uid": "1",

我想知道如何在没有唯一键作为嵌套数组前缀的情况下获得数据结构

Answer 1

问题是，如果您定义了键，json_encode 将读取它们。如果您不需要键，请声明不带键的数组。因此，您需要做的是根据所需的输出构建数组。

但是数据的排列方式使其难以正确格式化。我能看到的解决方案是做你已经在做的事情:

while($row = mysqli_fetch_assoc($result))   
{ 

  $uid = $row['UserID'];
  $name = $row['FirstName'].' '.$row['LastName'];
  $fiid = $row['FinancialInstID'];
  $fi = $row['FinancialInstName'];
  $acctID = $row['FIAccountsID'];


  $rows[$uid]['name'] = $name;
  $rows[$uid]['uid'] = $uid;
  $rows[$uid]['fi'][$fiid]['name'] = $fi;
  $rows[$uid]['fi'][$fiid]['acct'][$acctID]['name'] = $row['AccountCustomName'];

}

但随后您重新访问数组并使用 array_values 删除所有键:

foreach ($rows as $uid => $data)
{
    foreach ($data['fi'] as $fiid => $fi)
    {
        $rows[$uid]['fi'][$fiid]['acct'] = array_values($fi['acct']);
    }
    $rows[$uid]['fi'] = array_values($rows[$uid]['fi']);
}
// Here you format the outer array:
$rows = array(array('users' => array_values($rows)));

结果如下:

[
    {
        "users": [
            {
                "name": "Someones Name",
                "uid": "1",
                "fi": [
                    {
                        "name": "Testes",
                        "acct": [
                            {
                                "name": "Brothers"
                            },
                            {
                                "name": "Brothers"
                            },
                            {
                                "name": "Brothers"
                            },
                            {
                                "name": "Brothers"
                            },
                            {
                                "name": "Brothers"
                            }
                        ]
                    }
                ]
            },
            {
                "name": "Someones Name",
                "uid": "2",
                "fi": [
                    {
                        "name": "Testes",
                        "acct": [
                            {
                                "name": "Brothers"
                            },
                            {
                                "name": "Brothers"
                            }
                        ]
                    }
                ]
            }
        ]
    }
]
