how to run 'free -m' every minute & add to current page (php only)
<p>I need to </p>

<ul>
<li><strong>run</strong> 'free -m' every minute</li>
<li>and then <strong>add</strong> the result to the previous results</li>
</ul>

<p>So the script is going to run only of I call the free.php from my browser. I want to use <strong>php 5.3</strong> + <strong>javascript/AJAX</strong> + <strong>html</strong> only (=no cron, jQuery etc)</p>
