Thanks for the help!!
I still can't seam to get it to add a new user at the end of a line of
the selected site name.
Also how do I use the unset($users[3]) do I first have to determine
what number the one I what to delete is.
Here is what I have so far
$newuser="tester45";
$wanted_name="site7";
$groups= file("group");
$x = 0;
while(list($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++;
$handle = fopen("group2", 'a');
fputs($handle, $groups[$x]);
//here you could fputs to a temp file then copy to the original
// after finished
}
//Then write groups back to disk
