shorewall show zones

For a different purpose, I use php to format the output. This looks like 
the following function. the global var $shorewall_zones is an array of 
zone names which I would like to have in the output of the function, set 
in my config files. The function returns an array of these zones, where 
each zone itself is represented by an array of the hosts in it.

function shorewall__read_zones() {
        global $shorewall__zones;

        $done=exec('sudo /sbin/shorewall show zones',$zonestext,$rvar);
        $i=0; $zone=none; $zones=array();
        foreach ($zonestext as $entry) {
                if (substr($entry,0,1)==" ") 
                else $zone=trim($entry);
        foreach ($zones as $zname=>$zarray) {
                if (in_array($zname,$shorewall__zones)) 
        return $realzones;
