Something to try and do a progress bar.

progressbar.php

public function showProgress($total, $current, $message = '')
{
    $this->cachedMessage = str_repeat("\x08", strlen($this->cachedMessage));

    $percentComplete = ($current/$total);
    $completedCharacters = ceil($percentComplete * $this->totalProgressCharacters);
    $bar = str_repeat("*", $completedCharacters);
    $bar = str_pad($bar, $this->totalProgressCharacters, " ");
    $bar = "[" . $bar . "] ";

    $formatter = new \NumberFormatter('en_US', \NumberFormatter::PERCENT);
    $this->cachedMessage .= $bar . $formatter->format($percentComplete) . ($message ? " - " . $message : '');
    $this->logger->info($this->cachedMessage);
}
