PHP - Relative URL to Absolute URL

Question

I'm parsing HTML files and parsing out the links. Sometimes it comes accross something like:

./dir/dir/lol.html

My question is how do I turn this into an absolute url, the parser knows the URL that if found the link on.

For example:

parses: http://www.website.com/lol/index.html
find: ./dir/dir/haha.html

Then how can I combine this into:

http://www.website.com/lol/dir/dir/haha.html

why cant you do a str_replace('href="/','href="http : //www.website.com/',$completePage); on completePage, ignore the spaces in http : //, i kept them intentionally to prevent auto hyperlinking by SO — Eswar Rajesh Pinapala

You could use parse_url() to break URLs into their components most importantly PHP_URL_PATH to find out the path part of the URL.
