今天在调用方法时，发现返回值为：object，导致不能通过数组方式取值，捣鼓半天才知道这么取；
print_r(object);
(
[items:protected] => Array
(
[0] => stdClass Object
(
[user_id] => 488579
[user_type] => 1
[sex] => 1
[nick] => 自动化专用五
[phone] => 13111111115
)
[1] => stdClass Object
(
[user_id] => 494385
[user_type] => 1
[sex] => 1
[nick] => 123
[phone] => 15111111111
)
)
)
例：取第一组数据中 user_type的值
$user_type = $object[0]->user_type;
