You want a “nonce”, a unique value that is generated when the form is requested, then checked and invalidated when the form is submitted so that it can not be resubmitted.
There is already a question which discusses the FullThrottle nonce library for PHP, and another question about preventing the double-insert that typically happens when forms are submitted twice.
You should also be submitting the form via POST, and then redirecting the browser so that it requests the results via GET.
