title: Update ICU extension within xampp?
body: <p>I'm running <code>xampp</code> and I need to upgrade <code>ICU</code> (php_intl extension) to the latest version - I downloaded <code>54</code> from the ICU page but unsure how to go about upgrading it.</p>
  
  <p>There is a <code>bin</code>, <code>include</code> and <code>lib</code> folder - where do I put these files and do I have to do anything else?</p>
