我执行代码：

dump($_ENV);

结果并没有我在.env里面设置的 status=dev

但是我使用

dump(Env::get('status'));

就能取到值

这是啥情况呢？

有用谢谢

请教一下这是怎么回事

D:\wamp64\www\thinkphp\thinkphp\library\think\Debug.php:165:null

D:\wamp64\www\tp5\app\index\controller\Index.php:25:

array (size=0)

  empty

我的php.ini文件的variables_order值一直为"EGPCS"，但是输出的时候还是一个空数组

D:\wamp64\www\tp5\app\index\controller\Index.php:25:
array (size=0)
  empty

OK好了，还需要重启一下服务器

为什么修改了php.ini文件的variables_order值为"EGPCS"，还是不行呢

你可以修改php.ini文件的variables_order值为"EGPCS"。这时，$_ENV的值就可以取得了
