title: Find and delete all cache files on server
body: <p>I'm caching each page in its own directory rather than in a common directory:</p>
  
  <pre><code>www/contact/index.php
  www/contact/index.php.cache
  </code></pre>
  
  <p>It's simpler to implement but now I must clear each file manually.</p>
  
  <p>Ideally I'd like to run www/clear-cache.php and have it find and delete all files that end in <em>.php.cache</em> anywhere in www/</p>
  
  <p><em>I ask here cause I've already update the site and now I'm kinda in a hurry to clear the cache.</em></p>
