title: Removing X-Powered-By
body: <ol>
  <li><p>How can I remove X-Powered-By header in PHP? I am on an Apache Server and I use php 5.21.
  I can't use the header_remove function in php as it's not supported by 5.21. I used Header unset X-Powered-By, it worked on my local machine, but not on my production server.</p></li>
  <li><p>If php doesn't support header_remove() for ver &lt; 5.3, is there an alternative?</p></li>
  </ol>
