PHP/Apache/Informix questions...

Informix gurus: I'm interested in learning about/mucking around with PHP to access data that currently resides in a test Informix server. My current experience is with 4GL programs and/or SQL scripts that run locally, on the same box as the engine and the data. Our test set up is a mirror of a production box, running Informix OnLine Version 7.20.UC2, on HP-UX 10.20 Bringing up a web server on any of the HP boxes, test or production, probably isn't an option. The examples from the PHP manual involve PHP, Apache, and Informix all running on one Linux box. While I would like to bring up an instance of Informix on Linux at some point, I don't want to undertake that effort right now. We have a SuSE Linux box running Apache 1.3.9 that is used as a somewhat informal web server by our network operations center folks. This is the box that I would like to have PHP running on. So if PHP and Apache are running on the Linux box, how do I configure PHP's Informix driver to access the data that is on the HP box? Any advice/documentation would be greatly appreciated! ->Dan (dwade@superior.net)
