In our last episode, <ffik1p$n5g$1@gondor.sdsu.edu>, the lovely and talented
Fester Bestertester broadcast on comp.lang.php:

No PHP solution is possible to this problem. PHP works server-side. It has
no way of knowing what occurs in the browser. All can ever know is what
data is posted, and if the user does not submit the data, PHP must know
nothing.
