PHP and Informix

[Gurnox]

Right, I'm trying to connect to an Informix database via PHP. The PHP installation, as far as I can tell, is fine. phpinfo() says that informix is there and all is groovy.

I think the issue is that I don't have a DSN connection. How do I set this up under Linux? I have downloaded the relevant Informix drivers.

Any help much appreciated.
