Query formation question

[nca]

Is it possible to have this setup...

http://www.site.com/myfolder/
- have index.php stored in myfolder

Someone goes here:
http://www.site.com/myfolder/?see555
- have index.php see "see555" as a form post data

Maybe if there is any possible way for index.php to see "see555" as post data without making any changes to the server, I am on a shared one...

Just brain storming, please let me know your inputs. Thanks!

What are the contents of see555?

Sorry I meant this...
http://www.site.com/myfolder/?see555

I am trying to see if there is a way for index.php to be able to see "see555" as data. Just like it is post data from a form. Maybe if php has a function that shows what an incoming query's data is.
