Telegram Bot PHP keyboard doesn't works - bots

Question

I have a problem to creating a custom keyboard for my telegram bot.
Simply, it doesn't works and I don't know the reason...
This is my code:
<?
$botToken = "*****";
$website = "https://api.telegram.org/bot".$botToken;
$update = file_get_contents('php://input');
$update = json_decode($update, TRUE);
$chatId = $update["message"]["chat"]["id"];
$message = $update["message"]["text"];
$telegramusername = $update["message"]["from"]["username"];
$message_id = $update["message"]["message_id"];
$message_name = $update["message"]["chat"]["first_name"];
switch($message)
{
case "ciao":
funzioneCiao($chatId);
break;
case "youtube":
TastieraInline($chatId);
break;
default:
TastieraMenuPrincipale($chatId);
break;
}
function inviaMessaggio($chatId, $messaggio)
{
$url = "$GLOBALS[website]/sendMessage?chat_id=$chatId&parse_mode=HTML&text=".urlencode($messaggio);
file_get_contents($url);
}
function funzioneCiao($chatId)
{
$messaggio = "ciao";
inviaMessaggio($chatId, $messaggio);
}
function TastieraMenuPrincipale($chatId)
{
$messaggio = "ciaaaao";
$tastiera = '&reply_markup={"keyboard":[["Menu Principale"],["Developer"]]}';
$url = "$GLOBALS[website]"."/sendMessage?chat_id=".$chatId."&parse_mode=HTML&text=".$messaggio.$tastiera;
file_get_contents($url);
}
function TastieraInline($chatId)
{
$message = "Iscriviti subito";
$tastiera = '&reply_markup={"inline_keyboard":[[{"text":"SEGUIMI!","url":"http://www.youtube.com"}]]}';
$url = $GLOBALS[website].'/sendMessage?chat_id='.$chatId.'&parse_mod=HTML&text='.$message.$tastiera;
file_get_contents($url);
}
?>
Functions: "funzioneCiao($chatId);" and "inviaMessaggio($chatId, $messaggio)" works but,
"TastieraMenuPrincipale($chatId)" and "TastieraInLine($ChatId)" doesn't works.
I'm a beginner in PHP so I have a lot difficult...
Thank you.

I just tested the code, it works perfectly...

Why didn't you use CURL instead of file_get_contents(); ?!
just write this function into your code then call it after getting new updates :
function makeHTTPRequest($method, $types = []){
$url = 'https://api.telegram.org/bot'.$botToken.'/'.$method;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($types));
$res = curl_exec($ch);
if (curl_error($ch)){
var_dump(curl_error($ch));
} else {
return json_decode($res);
}
}
make sure CURL is activated on your hosting server!
