PDO bind error

Fiz este code para apagar banco de dados do mysql:

 public function deleteDatabase() {
 foreach ($_POST['marcar'] as $value) {
 $database[] = 'information_schema';
 $database[] = 'performance_schema';
 $database[] = 'mysql';
 $database[] = 'yuno-gasai';

 if (in_array($value, $database)) {
 exit ("You cannot delete that database.");
 } else {
 try {
 // Prepare the query to execute
 $query = $this->db->prepare( "DROP DATABASE `{$value}`", array(PDO::ATTR_CURSOR => PDO::CURSOR_FWDONLY));

 // Execute the query
 $query->execute();
 } catch(PDOException $e) {
 echo $e->getMessage();
 }
 }
 }
 }O code acima funciona certo!E acabei descobrindo que o bind pode ajudar no SQL injection:

 public function deleteDatabase() {
 foreach ($_POST['marcar'] as $value) {
 $database[] = 'information_schema';
 $database[] = 'performance_schema';
 $database[] = 'mysql';
 $database[] = 'yuno-gasai';

 if (in_array($value, $database)) {
 exit ("You cannot delete that database.");
 } else {
 try {
 // Prepare the query to execute
 $query = $this->db->prepare( "DROP DATABASE `:name`");

 $parameters = array(':name' => $value);

 // Execute the query
 $query->execute($parameters);
 } catch(PDOException $e) {
 echo $e->getMessage();
 }
 }
 }
 }

Depois disso ela exibi este erroWarning: PDOStatement::execute(): SQLSTATE[HY000]: General error: 1008 Can't drop database ''olá mundo''; database doesn't exist in C:\xampp\htdocs\application\model\model.php on line 121
