PHP正则表达式提取超链接及其标题,正则表达式超链接

有这么一段HTML,比较不规则的,如果要提取其中的链接地址和链接名称,怎么弄?

//HTML
$str = ''歌曲列表
中文金曲榜

• 轻音乐 '';

利用正则表达式是最简单的,其它的办法,偶米去想。。。

$pat = ''/(.*?)/i'';
preg_match_all($pat, $str, $m);

输出方法:

print_r($m[2]);
print_r($m[4]);

或者:
for($i=0;$i    echo ''

  • ''.$m[4][$i].'''';
    }

    显示结果是:

    Array ( [0] => http://list.mp3.baidu.com/song/A.htm?top8 [1] => http://list.mp3.baidu.com/list/bangping.html [2] => qingyinyue.html?top19 ) Array ( [0] => 歌曲列表 [1] => 中文金曲榜 [2] => 轻音乐 )

    于是,我们要采集某个网站的标题及链接地址方法就出来了。。。自己套用吧。。。
