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.) --- php > exec("/sbin/iptables -L INPUT -n -v -x -w", $iptables); php > var_dump($iptables); array(37) { [0]=> string(46) "Chain INPUT (policy ACCEPT 0 packets, 0 bytes)" ... ... --- $ cat foo.php <?php exec("/sbin/iptables -L INPUT -n -v -x -w", $iptables); var_dump($iptables); $ php foo.php array(37) { [0]=> string(46) "Chain INPUT (policy ACCEPT 0 packets, 0 bytes)" ... ... --- 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?
