I'm not exactly sure either which kind of makes this a difficult question....
What I'm trying to achieve is to make the pages look nicer in the address bar.
the URL:
mysite.com/index.php?page_name=questions
doesn't look as nice as
mysite.com/questions
and I'm certain in the PHP manual that there is some kind of a way to assign a directory like /question to a variable. I don't know how it worked but it seemed to make sense at the time. Something like IRC?
