Why isn't it displaying a value?

Question

PHP

Good evening everyone) There was a problem with the withdrawal. I have a two dimensional php array with data

$new = [
  '0' => [ 
    'header_title' => 'супер текст',
  'number' => '24324234242'
  ]
];

one person suggested to me how to simplify the output:

require_once("language.php");
$lang = 0;
$drill = array_values($new)[$lang];
echo "Заголовок: ".$drill->header_title;

But the value does not display(Please tell me what is the problem. I am not friends with PHP(Thanks in advance
