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：/
.*?/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
