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.='(.*)(.*)(.*)';
$k.='/isU';
preg_match_all($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
#(.*)#

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 的话建议你用jquery处理，它提供了多种选择器，类选择器，属性选择器...
test.php
$str=
html;
$pattern="/
preg_match_all($pattern,$str,$matches);
var_dump($matches[1]);
?>
$matches[1]就是你要的url数组
