Question

将我的JSON解码为数组并在其上使用print_r后，我看到以下输出：

Array
(
    [users] => Array
        (
            [0] => Array
                (
                    [id] => 197849982
                    [url] => https://somewhere.zendesk.com/api/v2/users/197849982.json
                    [name] => Some User
                    [created_at] => 2012-04-15T00:38:33Z
                    [updated_at] => 2012-06-08T07:53:03Z
                    [time_zone] => Sydney
                    [email] => email@email.com
                    [phone] => 
                    [photo] => 
                    [locale_id] => 1
                    [locale] => en-US
                    [organization_id] => 21520772
                    [role] => admin
                    [verified] => 1
                    [external_id] => 
                    [tags] => Array
                        (
                        )

                    [alias] => 
                    [active] => 1
                    [shared] => 
                    [shared_agent] =>

有更多输出，但我已将其截断。

我需要访问诸如'id'和'name'之类的值并将它们放入变量中，但我无法弄清楚如何在该数组中找到它们。我尝试了几种方法，每次都会遇到不同的错误。

如何访问此阵列中的数据？

Answer 1

这是你的意思吗？

$id = $data['users'][0]['id']

我认为你将拥有多个用户，所以我会做类似

的事情

$users = array();
foreach($data['users'] as $user){
  $users[$user['id']] = $user['name'];
}

Answer 2

假设您在该结果集中只有一个用户：

$user = $arr['users'][0];

$id = $user['id'];
$name = $user['name'];

如果你有更多，你想循环它们，那么：

$users = $arr['users'];

foreach($users as $user){
    $id = $user['id'];
    $name = $user['name'];

    // Do something with each user here
}
