I'm still a very fresh newbie on PHP and my problem seems really simple but I can't figure it out.
I have a website with the url http://www.mysite.com/a/index.html
Now I want to insert a link with PHP which changes the directory from 'a' to 'b', so the url of the link should look like http://www.mysite.com/b/index.html
The file name and the rest of the URL stay the same, it's really only the directory that's supposed to change.
Thanks in advance!
