Another way you can use to extract the information you need is through some 
type of regular expression (e.g.

<?
$url = "http://www.ashley.oviatt.whatever.com/"; // $_SERVER['HTTP_HOST']
$matches = array();
preg_match("/.*www\.(.*)\.com/", $url, $matches);
foreach ($matches as $match) { echo "Match: $match<br>"; }
?>

// Will print Matches: ashley.oviatt.whatever
)

You can widdle this down even further (there are million ways to write this 
regular expression), or just do a split on the . inside this string to 
capture the part that you really want from this.
