How to change the name of the buttons in the telegram bot?

Question

PHP

Hello, I'm interested in the question of how to change the name of the buttons in the telegram bot so that they are without "/" and that when you click on the button, exactly that command comes out.

function sendMessage($id,$text)
{
    global $api;
    $keyboard =  ;
  $resp = ["keyboard" => $keyboard,"resize_keyboard" => true,"one_time_keyboard" => false];
  $reply = json_encode($resp);
  $query = $api. '/sendMessage?chat_id='. $id .'&reply_markup='.$reply.'&text='.urlencode($text);
  file_get_contents($query);
}

You need to use inline_keyboard, or do this And in message processing, perform actions not only with "/help", but also with "help"
$keyboard = ;
