Ya know. You can look all you want, but for some reason, you never find
what you are looking for until you ask somebody and then keep
looking. Anyway, I found the answer. here it is:
$fc=file("/home/virtual/site$site_id/fst/etc/mail/local-host-names");
$key="#";
foreach($fc as $line){
if(!strstr($line,$key)){
}else{
echo "$line";
}
}
