preg_match_all("/<a\s*href='([^']*)'>(.*)<\/a>/isU",$str,$arr);
print_r($arr);$arr[1]即为连接，$arr[2]即为文字

Answer 3

哦。明白了。。你只要把每个li标签匹配到。再遍历不就行了。。第一个a标签为父类。后面的都为子类。

Answer 4

preg_match_all('/<li[^>]*>(.*)<\/li>/isU',$str,$arr);
print_r($arr);
foreach($arr[1] as $v){
     preg_match_all("/<a\s*href='(.*)'>(.*)<\/a>/isU",$v,$matches[]);
}
print_r($matches);
自己去看下结果就知道了。

Answer 5

我以为你字符串已经拿到了。。你前面再匹配上div就可以了。

Answer 6

foreach($arr[1] as $k=>$v){
     preg_match_all("/<a\s*href='(.*)'>(.*)<\/a>/isU",$v,$matches[]);
 foreach ($matches[$k] as $key=>$values){
$title =$matches[$key][2];
