Erreur fatale: constante de classe non définie
J'essaie donc d'utiliser cette classe de connexion mysqli (code ci-dessous) mais je reçois le message d'erreur: Erreur fatale: Constante de classe non définie 'DBUSER' [. ..] Je ne peux pas comprendre pourquoi parce que j'ai défini toutes les informations d'identification de connexion à la base de données et inclus le fichier de configuration.
Mon db.config.class.php:
class config {
public static $DBSERVER = "localhost"; // Set the IP or hostname of the database server you wish to connect to
public static $DBNAME = "**REMOVED**"; // Set the name of the database you wish to connect to
public static $DBUSER = "**REMOVED**"; // set the database user name you wish to use to connect to the database server
public static $DBPASSWORD = "**REMOVED**"; // set the password for the username above
public static $DBPORT = 3306;
public static $TABLEPREFIX = "";
}
