<?php
/* 
  V5.15 19 Jan 2012  (c) 2000-2012 (jlim#natsoft.com). All rights reserved.

  This is a version of the ADODB driver for DB2.  It uses the 'ibm_db2' PECL extension
  for PHP (http://pecl.php.net/package/ibm_db2), which in turn requires DB2 V8.2.2 or
  higher.

  Originally tested with PHP 5.1.1 and Apache 2.0.55 on Windows XP SP2.
  More recently tested with PHP 5.1.2 and Apache 2.0.55 on Windows XP SP2.

  This file was ported from "adodb-odbc.inc.php" by Larry Menard, "larry.menard#rogers.com".
  I ripped out what I believed to be a lot of redundant or obsolete code, but there are
  probably still some remnants of the ODBC support in this file; I'm relying on reviewers
  of this code to point out any other things that can be removed.
