Why is the Json file not being read?

Question

PHP

Hello, such a problem.
there is a file $peer_id.json And there is Php code
[{"id":522921916,"stage":"0"}]

$info = json_decode(file_get_contents('files/'.$peer_id.'.json'));
  $stage = $info->{'stage'};

As a result, the stage variable is empty, why?

Answer 1

$stage = $info[0]->{'stage'};
