Will this script work as it should?

Question

PHP

Will this script work in such a way that it sends a message to the telegram chat with the bot and notifies about the entrance to the site / transition to the link? And if so, how to connect it to the site so that it functions?

$BOT_TOOKEN = '-------------token from bot father ------------';
$to =  тид получателя;
$message = 'that you need ';
$parameters = array('chat_id' => $to, 'parse_mode' => 'HTML', "text" => $message);
$url = "https://api.telegram.org/bot" . trim($BOT_TOOKEN) . '/sendMessage?' . http_build_query($parameters);
$handle = curl_init($url);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($handle, CURLOPT_TIMEOUT, 60);
$response = curl_exec($handle);

Well, check it out. What bad can happen if you run this code?
At least I don't see you exposing the http method, which seems to be mandatory.

And if so, how to connect it to the site so that it would function

You wrap this code of yours in a function and use it in those places on the site where the "entry to the site / transition to the link" occurs

PS

В чём кайф использовать curl вместо объектно-ориентированных http-клиентов, типа того же guzzle?
