Besides the obvious, like security issues, character limits in older browsers, etc. Is there any real difference between $_POST and $_GET besides the method in which data is passed?
I have a script that works perfectly with $_POST but completely falls apart when I try to use $_GET. I rarely use $_GET but in this case I need to. I've never had this issue in the past and I've exhausted all my ideas on what to do next to troubleshoot it.
