Be aware... if you are using is_int() on posted form data if will ALWAYS return false (even if the
data is actually an int). If you know a field will always be a number and need to test for is_int
you have to do the following:
if(is_int($_POST['form_field'] + 0)):
// do something
endif;
Took me a while to work this one out!! Then suddenly remembered MySQL has similar quirks in some of
it's functions.
I assume $_GET vars are same, but not tested.

Reason: useless example
