php: convert all relative urls in absolute urls

Question

maybe this is an old question but i'm trying as a personal experiment to fetch a page form the web and the make a copy out of it with all the relative urls, links, href, src etc withn absolute urls

i'm using CURL to fetch hte page and I have now a $html variable that contains all the code..

so what; the next step? shoud i use preg_replace? how?

thanks

下一步是把它变成一个HTML解析器和遍历树，寻找和固定href上的属性a标签， src的属性img标签，等等等等解析器将能够重新发射的树作为一个字符串完成后。
