Telegram bot in PHP: why doesn't inline_keyboard send anything?

Question

Bots

I am writing a bot in PHP without libraries. Reached the inline buttons in the message:

$arInfo["inline_keyboard"][0][0]["callback_data"]=1;
$arInfo["inline_keyboard"][0][0]["text"]="Кнопка 1";
$arInfo["inline_keyboard"][1][0]["callback_data"]=2;
$arInfo["inline_keyboard"][1][0]["text"]="Кнопка 2";
send($data['message']['chat']['id'],"Примеры кнопок",$arInfo);

The problem is that when you click on any of the buttons in the bot, there is no request to the script. I'm trying to track like this:

$data = file_get_contents('php://input');
$data = json_decode($data, true);
$data_kb = json_decode($data->callback_query->data, true);

When you click on the button, a clock appears on it and nothing else happens.
Botfather inline mode is enabled.
Please tell me how to animate the inline_keyboard buttons. Thank you!

Answer 1

Inline_keyboard and inline_mode are different things.
You get a clock and nothing happens because you do not process the callback query in any way and do not return a response.
Try instead

$data_kb = json_decode($data->callback_query->data, true);

do
$data_kb = $data['callback_query'];
