<h2>Cache size</h2>
<p><?= $current ?> of <?= $max ?> bytes used. It's <?= (int) $percentUsed ?>% of available cache.</p>
<?php if ($percentUsed > 90): ?>
<p>Consider increasing <code>realpath_cache_size</code> in your php.ini.</p>
<?php elseif ($percentUsed < 50): ?>
<p>Consider decreasing <code>realpath_cache_size</code> in your php.ini.</p>
<?php else: ?>
<p>Everything seems to be OK.</p>

<h2>Cache TTL</h2>
<p>TTL is <?= $ttl ?> seconds.</p>
