Progress bars are not so hard. Inspired from http://forums.devshed.com/php-development-5/php-cli-progress-indicator-151590.html

progressbar.php

<?php
$max = 100;
for ($current = 1; $current <= $max; $current++) {
    $progress = "\r[%-{$max}s](%s/%s)";
    echo sprintf($progress, str_repeat("=", $current). '>', $current, $max);
    // replace echo with stdio of Aura, so we can make awesome colors also ;)
    usleep(6000);
}
