I have a script that submits form data via a "post" method to another
script. I have an href link in the destination script that links back
to itself for processing form data on that page with some "get" data
appended to the URL. I noticed that after clicking on that link and
sending the action back to itself, a check of isset($_POST) returns
true while displaying the content of $_POST displays an empty array.
I had expected isset($_POST) to return false, thinking the script
would unset the $_POST array when the <a> link sent it back to
itself. Instead, it leaves $_POST set but empty.
What is the convention here?
