preg_match and regular expressions

Question

I am trying to get website adresses from a webpage. The pattern is always:

    <br />i <a href="http://www.website.com"

The part I need is www.website.com. After reading a lot I made this;

    "preg_match('@^(?:<br />i <a href="http://)?([^/]+)@i' , $html, $matches);"

but I think I made a mistake... Someone who can help me ?

I've put my "solution" between brackets because stackoverflow makes a mess of it...

尝试这个：

preg_match( '/<br \/>i <a href="http:\/\/([^"]+)"/', $html, $matches );
