Input filtering does not solve the problem ifsetor() is designed to
solve.  It tackles a small part of it, but ifsetor() is a general purpose
construct that is used for $_GET, $_POST, as well as ANY OTHER array
element or variable in your script.

  $x = ifsetor($somearray[$foo][$bar], 0);

Is a lot cleaner than:

  $x = isset($somearray[$foo][$bar]) ? $somearray[$foo][$bar] : 0;

ifsetor()'s purpose is simple and clear:

To return a variable value if it exists or a default value if it does
not exist WITHOUT generating any error.

Thanks.
