directory list and url

[f8ball]

I'm creating a page that allows users to view the contents of a particular directory. I've set up the list to link to it's specific directory. The addresses should be [url]http://whatever.com,[/url] but for some reason they are coming up http://www.whatever.com so the page can be accessed. Is there some way of stripping the www? I've tried ereg_replace and other options, but nothing seems to work. Thanks for any comments.

<?php
$dir = "../mydir/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
		$url = "http://myurl.com";
            print "<a href=\"$url/mydir". $file. "\" target=\"_blank\">$file</a><br>";
        }
    closedir($dh);
    }
}
?>

I'm sure there is a way to do this in one regular expression, but here's something to try:

$url = "http://www.whatever.com";
$newurl = eregi_replace("[[:alpha:]]+://", "", $url);
$newurl = eregi_replace("www.", "", $newurl);

This should output just the domain name (whatever.com).
