    {
        $connection = DB::connection()->getDatabaseName();

        if ($connection) {

            $database = DB::connection()->getDatabaseName();
            
            dd("Connected successfully to database " . $database . ".");
        }
    }
}

    {
        try {
          
            $database = DB::connection()->getDatabaseName();

            dd("Connected successfully to database " . $database . ".");
