How to get photo in real size (not thumb) from telegram?

Question

I am using getFile() and then download photo with a link like https://api.telegram.org/file/bot/. But I received only his thumbnails

Answer 1

if you use PHP: you can write this line for full size:

$file_id = $updates['message']['photo'][1]['file_id'];

and this line for thumb:

$file_id = $updates['message']['photo'][0]['file_id'];
