Hmm.  I can't replicate this failure.  Using both `php -a` and foo.php,
I get expected results. (I'm using the INPUT chain because that's what
I have with real rules.)

   $ cat foo.php

   var_dump($iptables);
   $ php foo.php
   array(37) {

I noticed that your path to iptables is in /usr/bin/, but `which` on my
system says /sbin/.  Are you running this as root?  What version of PHP
are you using?
