List all firewall rules

Hi all,
I want to wite a php cli script to show all firewall rules.
the following code doesn't print anything. I have 3 rules.
can you help me?


$a_filter = &$config['filter']['rule'];

for ($i = 0; $i < count($a_filter); $i++) {
printf("num:%d", $i);

}

How do you invoke the script?

How does $config get initialised?

Thank you
My initialization was incorrect.

jimp

#!/usr/local/bin/php -q
require_once('config.inc');
global $config;
$a_filter = &$config['filter']['rule'];

for ($i = 0; $i < count($a_filter); $i++) {
printf("num:%d", $i);

}
?>
