Undefined array key "REMOTE_ADDR" in laravel octane

I am using laravel 8. Before upgarding to octane I was getting ip address in $_SERVER['REMOTE_ADDR']. After changing to octane there is no such index in $_SERVER.

I am using this variable in validator of register controller ,while new user is registering to app.

 protected function validator(array $data)
      {
 dd($_SERVER['REMOTE_ADDR'])
}

when I dump $_SERVER I am getting this array (I am hiding app details.)

  "LARAVEL_OCTANE" =>"1"
  "APP_BASE_PATH" => "xxx"
  "JOURNAL_STREAM" => "xxx"
  "PATH" =>"xxx"
  "INVOCATION_ID" => "xxx"

Solution

I have found the solution for this problem. As @Rwd commented replaced $_SERVER['REMOTE_ADDR'] by request()->ip()

and it works correctly . (In octane the global variables of PHP will not be initialized when the request is initialized, such as$_ SERVER, $_ POST, $_ Get, etc.. Got details from following article. https://developpaper.com/php-fpm-vs-swoole/)
