Get current domain
<p>I have my site on server </p>

<p><strong>http://www.myserver.uk.com</strong></p>

<p>For this i have two domain:</p>

<p><strong>http://one.com</strong></p>

<p>and </p>

<p><strong>http://two.com</strong></p>

<p>i would like get with PHP current comain, but if i use <strong>$_SERVER['HTTP_HOST']</strong> then this show me 
<strong>myserver.uk.com</strong></p>

<p>instead of</p>

<p><strong>one.com</strong> or <strong>two.com</strong></p>

<p>How can i get domain, not the server name? I have php version 5.2</p>
