Answer 2

一次匹配，也可以分开匹配
preg_match('#<a.+?href="(.+?)".+?src="(.+?)".+?<span class="s1">(.+?)</span>\s*<span class="s2">(.+?)<.+?<p class="star">([^<]+)#s', $s, $m);
print_r($m);

Answer 3

http://www.360kan.com/dianying/list.php 源代码地址 您看下  您给的正则无关的内容也给匹配出来了- -

Answer 4

让他显示内容 不显示html代码 麻烦您给修改下

Answer 5

preg_match('#<a.*?href="(.*?)".*?src="(.*?)">.*?<span class="s1">(.*?)</span>.*?<span class="s2">(.*?)</span>.*?<p class="star">(.*?)</p>#is',$str,$arr);
var_dump($arr[1],$arr[2],$arr[3],$arr[4],$arr[5]);
你要的5个ok了
