   3   * MySQL improved driver (mysqli)
   4   *
   5   * This is the preferred driver for MySQL connections. It  supports both
   6   * transactional and non-transactional table types. You can use this as a
   7   * drop-in replacement for both the mysql and mysqlt drivers.
   8   * As of ADOdb Version 5.20.0, all other native MySQL drivers are deprecated.
   9   *
  10   * This file is part of ADOdb, a Database Abstraction Layer library for PHP.
