Install error / difficulties

I have downloaded .phar file. I have added it to my code:

    require_once 'madeline81.phar';
/*
    if (!file_exists('madeline.php')) {
        copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
    }
    include 'madeline.php';
*/
    $MadelineProto = new \danog\MadelineProto\API('session.madeline');
    $MadelineProto->start();

    $me = $MadelineProto->getSelf();

    $MadelineProto->logger($me);

    if (!$me['bot']) {
        $MadelineProto->messages->sendMessage(peer: '@stickeroptimizerbot', message: "/start");

        $MadelineProto->channels->joinChannel(channel: '@MadelineProto');

        try {
            $MadelineProto->messages->importChatInvite(hash: 'https://t.me/+Por5orOjwgccnt2w');
        } catch (\danog\MadelineProto\RPCErrorException $e) {
            $MadelineProto->logger($e);
        }
    }
    $MadelineProto->echo('OK, done!');

I have removed top lines as I don't think it needs to be done because I have included phar-file, correct?

This is the error I get:

I get banned from Telegram channel when I post this. Your docs ask to post problems, instantly getting kicked is not nice. Please advise.
