I think I can get this...

两者都被允许. "use ArrayObject" == "use \ArrayObject"
"use ArrayObject" 或 "new \ArrayObject" 是标准做法.

use ArrayObject;
和
use \ArrayObject;
应该使用哪一个？

Description:
------------
---
From manual page: https://php.net/language.namespaces.importing
---

$a = new ArrayObject(array(1)); // 实例化 ArrayObject 对象
// 如果不使用 "use \ArrayObject"
，则实例化一个 foo\ArrayObject 对象


Test script:
---------------
use \ArrayObject 
use ArrayObject
都能引入全局类
