我想获得accout ID

Answer 1

$account = Array(
    'ID' => 4,
    'account_name' => 'HANDSOME'.
    'nickname' => 'PROGRAM',
    'email' => 'JAMPONG@ya.com',
    'type' => 1);
$account_id =  $account['ID'];

Answer 2

$id = $this->session->userdata('account');首先$id不是像设置一样保存数组值的好名字，

所以这样的事情会很好：

$account = $this->session->userdata('account');

然后访问id：

$account['ID'];
