add http:// in front of www. urls

[Anon]

How do I make sure that all website URLS added to the database have http:// in front of them, and if they dont, then add http:// in front. Because when i make a url out of these website address, what hapeens is that the ones beginning with www. get www.myserver.com/www.theriserver.com

which i dont want

Thanks

maybe try

if (strpos($url, 0, 7) != http://)
$newurl = "http://" . $url;
