What's the problem? Help solve

Answer 1

what is the problem - says the interpreter. accessing non-existent properties of an object. these fields did not come to json.

Answer 2

Do It:

echo '<pre>';
print_r($data);
echo '</pre>';

Answer 3

100% working...
$callbackData = file_get_contents(" php://input ");
$ac = json_decode($callbackData, true);
if (isset($ac["message"]))
{
//Information about the sender of the command
$idMessage = $ac['message']['message_id'];
$fromGroup = (empty($ac['message']['chat']['id'])) ? 0 : $ac['message']['chat']['id'];
$fromUser = $ac['message']['from']['id'];
$from = ($fromGroup != 0) ? $fromGroup : $fromUser;
$user_info = $ac['message']['from'];
$command = $ac['message']['text'];
} else if (isset($ac["callback_query"
$fromGroup = (empty($ac['callback_query']['message']['chat']['id'])) ? 0 : $ac['callback_query']['message']['chat']['id'];
$fromUser = $ac['callback_query']['from']['id'];
$from = ($fromGroup != 0) ? $fromGroup : $fromUser;
$user_info = $ac['callback_query']['from'];
$command = $ac['callback_query']['data'];
$editMessage = true;
}

Answer 4

Read the Telegram Bot API documentation . It indicates which fields are optional. Add processing of such fields, for example, through null-coalescence:

'lastname' => $data->message->from->last_name ?? null,
