Probleme Data in Date-Bank zu einsetzen

[liebewinter]

Wegen das Fehler mit,

$db->close();
   return $ok;

hier sagt eine losung..mit $this->db = null;

Wie jetzt meine writeCommentToDatabase() habe,

function writeCommentToDatabase()
    {
          // Establish connection with MYSQL Server
          try
          {
             $db = new PDO("mysql:host=localhost;dbname=meine", "root", "pass");
          }
          catch (PDOException $pe)
          {
             echo "<br>Cannot connect to database: " . $pe->getMessage();
             return false;
          }

          //Prepare Query of SQL
          $statement = $db->prepare("INSERT INTO mela(name, email, message, datetime, ips) VALUES (:name, :email, :message, :date, :ips)");
          if (!$statement)
          {
             echo "<br><br>prepare failed: SQLSTATE=" . $db->errorCode() . ", Error Info=" . print_r($dbh->errorInfo(), true) . "</p>";
             $ok = FALSE;
          }
          else
          {
             $ok = $statement->bindValue(':name', $this->Name, PDO::PARAM_STR)
                && $statement->bindValue(':email', $this->Email, PDO::PARAM_STR)
                && $statement->bindValue(':message', $this->Message, PDO::PARAM_STR)
                && $statement->bindValue(':date', date("Y-m-d H:i:s"), PDO::PARAM_STR)
                && $statement->bindValue(':ips', $this->ips, PDO::PARAM_STR);
             if (!$ok)
             {
                echo "<br><br>bindValue failed: SQLSTATE=" . $db->errorCode() . ", Error Info=" . print_r($dbh->errorInfo(), true) . "</p>";
             }
          }
          if ($ok)
          {
             $ok = $statement->execute();
             if (!$ok)
             {
                echo "<br><br>execute failed: SQLSTATE=" . $db->errorCode() . ", Error Info=" . print_r($dbh->errorInfo(), true) . "</p>";
             }
              
       
          }
          echo "<br/><br/><span>Data Inserted successfully...!!</span>";
        $this->db = null;
        return $ok;
         
       }    

Die Daten wird noch nicht auf meine Webseite geschrieben...
