It seems like $real can also be of type null; however, parameter $real_usage of memory_get_peak_usage() does only seem to accept boolean, maybe add an additional type check?

        return sprintf('peak: %s', $this->convert($memUsage));

        return @round($size / 1024 ** ($i = floor(log($size, 1024))), 2).' '.$unit[(int) $i];
