stripping chars if exist

[adammc]

Hi folks,

Im using <?php echo $_SERVER['HTTP_HOST'];?> to get the users domain name for use in a form.

The problem is I only want to get their domain and not the www.

If they use 'www.' to get to the form then 'HTTP_HOST' contains a www.

How can I check to see if it exists and strip is away?

i got it sorted using:

$str = preg_replace('/^www\./','',$_SERVER['HTTP_HOST']);
