        $_SESSION['pages']=1;//this is when user is login as admin
    }else{

I would go with something like:

if(isset($_GET['home'])){
  if(isset($_SESSION['valid_user'])) {
    $_SESSION['pages']=0;//this is when user is not login
  } else {
    if(isset($_SESSION['valid_admin'])) {
      $_SESSION['pages']=1;//this is when user is login as admin
    } else {
      $_SESSION['pages']=2;//this is where user is login or Visitor
    }
  }
}

and in that case you only set the according $_SESSION member.
