c# - Using operator sealed with the members of the class -

-

i've found in troelsen's book, operator sealed can used on members of class protect virtual methods override.

but if don't want override virtual methods, sense make virtual?

you might have situation this:

public class {     public virtual void mymethod()     {         //...     } }   public class b : {     public override void mymethod()     {         //...     } }   public class c : b {     public override void mymethod()     {         //...     } }

but if want inheriting class c not able override b's mymethod, while still allowing b override a's? can do:

public class b : {     public sealed override void mymethod()     {         //...     } }

with change made, can no longer override method in c.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
