I'm having an annoying :)

I use regexes from this: http://forums.codecharge.com/posts.php?post_id=77123

if you enter [url]www.bob.com[/url] it leads too http://localhost/test/www.bobsbar.com

So I added before http://$1 in the replacement. That fix it but then [url]http://www.bob.com[/url] will lead to http://http://www.bobsbar.com

How would you fix this? I want my users to be able to post links with AND without http:// and i want it to redirect to the site -_-

Hope you understand this.

Edit

function bbcode_format($str)
{
$str = htmlentities($str);

$find = array(  
    '/\[url\](.*?)\[\/url\]/is', // hyperlink
    '/\[url\](http[s]?:\/\/)(.*?)\[\/url\]/is' // hyperlink http-protocol
);

$replace = array(
    '<a href="$1" rel="nofollow" title="$1">$1</a>',
    '<a href="$1$2" rel="nofollow" title="$2">$2 THIS WORKS</a>'
);

$str = preg_replace($find, $replace, $str);  

return $str;
}

both www.bob.com and http://www.bob.com uses the first replacement
