Code to turn URL into Domain

[Scooter]

I am looking for a bit of code for a PHP page.

I want to be able to turn any URL string into a domain name with all the extra crap removed.

Examples:
From URL String: http://www.any-domain.com/contact.php
into domain: any-domain.com

or URL String: http://www.any-domain.co.uk/dir/page.php
into domain: any-domain.co.uk


Thanks


Edit: fix examples

This is a nice site that has a set of useful regular expressions for all sorts of purposes. I modified one from their URI section.
http://www.regexlib.com/DisplayPatterns.aspx?cattabindex=1&categoryId=2

Here's the code:

$str = "http://www.any-domain.co.uk/dir/page.php";
$regex = "[a-zA-Z0-9]+[\.]?(([a-zA-Z0-9\.\-]+)?\.(com|org|net|mil|edu|co.uk))";
eregi($regex,$str,$grab);
echo $grab[1];

Should get the job done... just add any other extensions you want to check for.

RETURN 1: any-domain.co.uk
RETURN 2: any-domain.com

I was testing something and I came up with this (which might also be useful to you). The following PHP code will take an external text document, and return a list of all the domains it finds in it.

$myfile = file("C:/sample.txt");
$myfile = addslashes(implode("",$myfile));
$regex = "/([a-z0-9]+[\.])?(([a-z0-9\.-]+)\.(com|org|net|mil|edu|co.uk))/i";
preg_match_all($regex,$myfile,$grab);
while(list($key,$value) = each($grab[2])) echo $value."<br>";

The following will alphabetize the list and remove duplicates.

$myfile = file("C:/sample.txt");
$myfile = addslashes(implode("",$myfile));
$regex = "/([a-z0-9]+[\.])?(([a-z0-9\.-]+)\.(com|org|net|mil|edu|co.uk))/i";
preg_match_all($regex,$myfile,$grab);
$final = $grab[2];
asort($final);
reset($final);
$temparr=$final;
 while(list($key,$value) = each($final))
 {
   if(!empty($prevkey))
     if($value==$final[$prevkey]) unset($temparr[$key]);
   $prevkey = $key;
 }
$final = $temparr;
while(list($key,$value) = each($final)) echo strtolower($value)."<br>";

You can use the DNAuction page html as a test sample:

easiest way is to use frame

just use the built in php function
parse_url ( string url), it will seperate your url in to a component array; for the current page use: parse_url ( $PHP_SELF).
The important array components will be:
[host]: www.your_domain
and [path]: somepage.php.
So just strip out the www. from the host with a reg exp.

If interested in a javascript version, see a similiar script to expose just the domain name on mouseover, at http://www.choicenames.com/linkstripper.html, should be easy to break the script down to return just what you want to see.
