У кого WS отвалились из-за php7.3
заменить 134 и 158 строки

 $this->allsockets = array_filter($this->allsockets, fn($s) => $s !== $socket);

на

$this->allsockets = array_filter($this->allsockets, function ($s) use ($socket) {
    return $s !== $socket;
});

Спасибо за наводку. Сейчас должно быть ок.
