Bonjour suite au tutoriel L'objet PDO en PHP j'ai désider de maître a jour le code du site que je suis en-train de créer.

Voici l'erreur :

Voici le code :

class SggCms {

   */
  public $cpconnect;
  /**
   * variable du cms.

   */
  public $sggcms;
  function connect($id) {
    global $cpconnect;
    try {
      $DB = new PDO("mysql:host={$cpconnect$id]'host']};dbname={$cpconnect$id]'database']}", "{$cpconnect$id]'user']}", "{$cpconnect$id]'password']}");
      $DB->exec("SET CHARACTER SET {$cpconnect$id]'encoding']}");
      $DB->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
    } catch (PDOException $e) {
      echo "The database is not available, please try again later. <br/> Error code: " . $e->getMessage() . "<br>"
      . "La base de donnéer n'est pas disponible, Merci de rééssayer plus tard.<br/>Code erreur: " . $e->getMessage() . "<br>"
      . "La base de datos no está disponible, por favor inténtelo de nuevo más tarde. <br/> Código de error: " . $e->getMessage();
