I looked at the main page and saw that nothing was really about security, at least not much, so I decided to post something.
I recently heard about the php post exploit, and I gotta tell you, it really confuses me, I always use the post method because that way when I have somebody fill out a form it doesn't put all their answers in the address bar. So what I don't understand is how people can exploit the post method, because post doesn't put anything in front of the user to manipulate, I know how get requests can be changed to do some odd things, since get requests put all the input in the address bar, but I really don't understand how this post exploit works. I don't want to know how to exploit pages, but basically, could somebody go around and screw with my server because I use post?? Thanks. By the way, I would say I'm an intermediate user of php, so plz don't post something over my head.

EDIT:
Sorry about the misleading title
