<?php
/* 
  V4.80 8 Mar 2006  (c) 2006 John Lim (jlim@natsoft.com.my). 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.

Tested with PHP 5.1.1 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.
