your groups array will look like this
groups[0] = site1:x:503:tester1
groups[1] = site2:x:504:tester2,tester2a
so loop through the array
$x = 0;
while(list($key,$val) = each($groups)){
//you need split the array values like this
list($name,$pass,$gid,$user_list) = split (":", $groups[$x]);
//see if we have the right one
if($name = $wanted_name){ //site6
//then split the usernames into a sub array
$users = explode(',',$userlist);
// to add
$users[] = $newuser;
// to delete
unset($users[3])
// now add it back
$userlist = implode(',',$users)
$list = $name.':'.$pass.':'.$gid.':'.$userlist;
$groups[$x] = $list;
}
$x++;
//here you could fputs to a temp file then copy to the original
// after finished
}
Then write groups back to disk
