How to enable fileinfo.so
<p>i am using xampplite1.7.2 which is using PHP 5.3 but when i use the fileinfo function its giving me error </p>

<blockquote>
  <p>Call to undefined function
  finfo_open()</p>
</blockquote>

<p>I don't know rather my fileinfo.so is enabled or not. So please someone guide me how to check and how to enable it if its not enabled.
Thanks</p>
