上面是分类  我匹配的一级分类
$dafht='#<h4 class="cat-hd fst-cat-hd (.*)category-(.*).htm\?search\=y\&catName\=(.*)">(.*)</a></h4>#iUs';
preg_match_all($dafht, $fenlei, $dafenlei);

但是无效 求大神解答  


一级分类主要是采集   category-907362761.htm     这个数字ID  和后面的名称

二级分类采集   category-907362761.htm    parentCatId=907362759  这俩个数字ID  和后面的名称

怎么写 卡主半天了 求解答

为什么费神写这个？人家网站稍有变化，功夫就白费了
网上有很多简捷实用的工具，为什么不用呢？
比如这个
