title: Upgrade current XAMPP 1.6.8 with PHP 5.3
body: <p>I'm running XAMPP 1.6.8 on Windows 7 Ultimate and I wonder how can I upgrade my current installation with PHP 5.3.x without changing the whole XAMPP. </p>
  
  <p>Can I just download PHP 5.3 from php.net and replace the PHP folder inside XAMPP?</p>
