How to select options in json_decode in php?

Question

PHP

json_decode returns an array with data when I make a selection - the variable is empty:

<?php
header('Content-Type: text/html; charset= utf-8');

$token = 'МОЙ ТОКЕН';
 $api = 'https://api.telegram.org/bot' . $token;
 
    
    $output = json_decode(file_get_contents($api . '/getUpdates'), TRUE);
    
    //var_dump($output);
    $message = $output['message']['text'];
    echo 'Текст' . $message;
    
?>

Answer 1

What does var_dump($output); show?
The variable is empty because there are no such keys in the array and will not be, because getUpdates returns something else.
