....this. Where's "verb" in your URI? Make sure you're posting real
examples. If this is real, it looks like something external is re-
arranging your request variables in ways that we cannot predict.

Well, you have two options--you can either use the PHP-method of passing
multiple values to the same parameter name:
myapp.php?a[]=12&a[]=12
which will yield a two-element array, or if that's not an option, you can
parse the URI yourself using $_SERVER variables.

$_REQUEST should not === null in this case. Methinks something (in your
function library perhaps) is mucking with your variables before your
testing.
