PHP communicating with UniData Database

Question

I want to write a PHP script that can retrieve information from UniData Database which is hosted on a different server.

I came across this script:

<?php
  $UdSession = new COM("UniObjects.unioaifctrl");
  $UdSession->HostName = "192.168.0.1";
  $UdSession->AccountPath = "c:\ibm\mydemoaccount";
  $UdSession->UserName = "admin";
  $UdSession->Password = "password";
  $UdSession->Connect();
?>

I downloaded asjava.zip from http://trac.spatialytics.com/geokettle/browser/trunk/libext/JDBC/asjava.zip?rev=1

and placed the unzipped folder in the root directory of my source code.

When I tried to run this php script, I encountered error as such: Failed to create COM object UniObjects.unioaifctrl

Please let me know how I can rectify the problem.

Additionally, my localhost is currently running on Windows. Eventually I wish to run the code on Mac OS. I heard about using UniObjects for Java. Where can I download this library and how do I incorporate this library in my code?

Thank you.
