以上代码中我只想要(.*)和这个格式一样的URL。这正则怎么写。

以下是我写的，
$html=file_get_contents($setting['book_url']);
$k='/

(.*)(.*)';
$k.='/isU';
preg_match_all($k,$html,$rs);
没有匹配到地址

回复讨论(解决方案)

preg_match_all('#(.*?)#i',$html,$rs);

那直接写就是了
#(.*)#

(.*)

(.*)(.*)';
$k.='/isU';
preg_match_all($k,$html,$rs);
没有匹配到地址
那是当然啦你的正则表达式是‘/

(.*)

(.*)(.*)/isU’

之后的.*不匹配换行符，而html代码中

后面有若干空格还有换行符
要是你想获取class="main_con"的ul里面的
