Why is $bot->run(); used in telegram?

Question

PHP

Actually, subject. After all, if I use the $bot->sendMessage or $bot->sendPhoto function, then everything works anyway. What function does $bot->run(); then perform?
And if it is necessary, then in the case when I have several teams in a row, put wounds after each or after the last team?
Update . I use https://github.com/TelegramBot/Api

Answer 1

You can look at the source code and find the run() method

/**
     * Webhook handler
     *
     * @return array
     * @throws \TelegramBot\Api\InvalidJsonException
     */
    public function run()
    {
        if ($data = BotApi::jsonValidate($this->getRawBody(), true)) {
            $this->handle([Update::fromResponse($data)]);
        }
    }

As you can see, this method looks to see if valid JSON data came with the request and tries to process the incoming request. Those. this method is needed to process incoming requests to the bot.
To send messages not in response to an incoming message, but initiated somehow else, for example, by a timer or simply by running a script from the command line, you do not need to wait for incoming requests.

To start a bot and receive messages from it
