Fatal error: Call to undefined function

[Anon]

When we run the script at the root or with a regular login the script runs great.

When trying to run from a webpage (.php) we get:
Fatal error: Call to undefined function...

How come the script runs on the server at the root and not through the web?

We are running PHP Version 4.0.5

The shared object we are trying to use shows up as a module.

Thanks, Chris
