$html = <<<TTT<!DOCTYPE html><html>    <head>test</head>    <body>                    <a id="a5" href="111">wawa</a>            <a id="a6" href="222">hehe</a>            <a id="a7" href="333">haha</a>            <a id="a8" href="444">uuuu</a>              ......        <b>            <a id="a1" href="111">wawa</a>            <a id="a2" href="222">hehe</a>            <a id="a3" href="333">haha</a>            <a id="a4" href="444">uuuu</a>        </b>                   ........    </body></html>TTT;preg_match_all('@<b>([^`]*?)<\/b>@i',$html,$match);preg_match_all('@href="(.+?)"@i',$match[0][0],$matches);var_dump($matches);

这是先把里面的
先匹配出来,然后在匹配出href
有没有一个正则就匹配到的方法?

一个正则,我没有这个本事。
不过除了正则,还可以用dom解析,包括simplehtmldom

有没有能用一个正则就匹配出来的呢?

~\s*(]+href="(.*?)">.*?)*?\s*~msi

大体如此,自己调一下
