PHP PDO: charset, set names?

Question

I had this previously in my normal mysql_* connection:

mysql_set_charset(\"utf8\",$link);
mysql_query(\"SET NAMES \'UTF8\'\");

Do I need it

Answer 1

I test this code and

$db=new PDO('mysql:host=localhost;dbname=cwDB','root','',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
$sql="select * from products  ";
$stmt=$db->prepare($sql);
$stmt->execute();
while($result=$stmt->fetch(PDO::FETCH_ASSOC)){                  
    $id=$result['id'];
}
