Question

我有一个jSON文件，我想显示它的数据，但它显示我的结果有一些奇怪的格式，我不知道我哪里错了。这是我的PHP代码，

$json = file_get_contents('data.json'); 
$data = json_decode($json,true);
$users = $data['user'];
foreach($users as $user)
{
echo $user['user'];
}

我的jSON文件中的数据，

{
"user":
    {
    "id":"#79F9FFB1EE0CB1CC",
    "user":"test@mail.com",
    "password":"123456",
    "email":"test@mail.com",
    "name":"John Doe",
    "creationDate":1387111401
    },
"status":
    {
    "version":"0.9.9.1",
    "command":"getuser",
    "opf":"json",
    "error":false,
    "code":0
    }
}

Answer 1

这是你的foreach循环错误。

您只有用户才能通过以下方式替换您的循环：

$users = $data['user'];
echo $users['user'];

Answer 2

$json = '{
"user":
    {
    "id":"#79F9FFB1EE0CB1CC",
    "user":"test@mail.com",
    "password":"123456",
    "email":"test@mail.com",
    "name":"John Doe",
    "creationDate":1387111401
    },
"status":
    {
    "version":"0.9.9.1",
    "command":"getuser",
    "opf":"json",
    "error":false,
    "code":0
    }
}';

$data = json_decode($json,true);
$users = $data['user'];
foreach($users as $key=>$user)
{

 echo $user.'<br>';
}

使用JSON和PHP显示用户数据
