Почему не работает EvTimer?

Question

[linuxoid_inrus]

Есть такой код у телеграм бота, нужно через 2 секунды сохранить файл для примера, но он не создается. В /ext/php/7.2 у cgi, cli, apache2 в php.ini прописал extension=ev.so. Идей отловить ошибку нет.

case "/timer":
                $w1 = new EvTimer(2, 0, function () {
                    file_put_contents("timer.txt", "all works but chatID is: ");
                });
                Ev::run();
                break;
