How can I make a countdown timer in PHP?
<p>How can I make a countdown timer in PHP which starts at 40 seconds and counts in this format:</p>

<blockquote>
  <p>40.59 - 40.48 - 40.47 - etc etc</p>
</blockquote>

<p>I also need a button that resets it.</p>

<p>Is this possible in PHP? Do I need to use JavaScript?</p>
