title: PHP built-in development server: disable caching
body: <p>Sometimes I like to use PHP's built-in development server to work on quick stuff like so:</p>
  
  <pre><code>php -S 127.0.0.1:8888
  </code></pre>
  
  <p>However I seem to run into heavy caching issues from time to time where I need to restart the server in order to see even simple HTML changes.</p>
  
  <p>I haven't been able to find any options to disable this or otherwise pinpoint what might be causing this frustration.  </p>
  
  <p><strong>Note:</strong> I usually have Chrome's Developer Tools open with browser caching disabled while I'm doing this.  I don't think it's a browser caching issue. </p>
  
  <p>Is there anything I can try?</p>
