select_database always returns false

[JamesWilson19947]

Hi,

Unless I'm missing something obvious, this function always returns false?

    /**
     *  Selects the default database for queries.
     *
     *  <code>
     *  // set the default database for queries
     *  $db->select_database('database_name');
     *  </code>
     *
     *  @param  string  $database   Name of database to select as the default database for queries.
     *
     *  @since 2.9.4
     *
     *  @return boolean     Returns TRUE on success or FALSE on failure.
     */
    public function select_database($database) {

        // if no active connection exists, return false
        if (!$this->_connected()) return false;

        // update the value in the credentials
        $this->credentials['database'] = $database;

        // select the database
        mysqli_select_db($this->connection, $database);

    }
