上面是分类 我匹配的一级分类
$dafht='#

(.*)

#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








回复讨论(解决方案)

一级分类:/.*?<\/h4>/isU,没测试,不知道能不能匹配到

二级分类看不太清楚

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
