preg_match和正则表达式

Question

I am trying to get website adresses from a webpage. 我正在尝试从网页获取网站地址。 The pattern is always: 模式始终为：

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

The part I need is www.website.com. 我需要的部分是www.website.com。 After reading a lot I made this; 看了很多书后，我做了这个。

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

but I think I made a mistake... Someone who can help me ? 但是我想我做错了...有人可以帮助我吗？

I've put my "solution" between brackets because stackoverflow makes a mess of it... 我把我的“解决方案”放在了方括号之间，因为stackoverflow使它一团糟。

尝试这个：

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