That may be exactly the reason they have the splash screen pop up.

You can look at their ION product, which will do what you want.
You can of course call IDL from the command line with a procedure to run,
but if I remember correctly, I think IDL stays open.

Another thing to do would be have IDL poll and wait for input from the php
program (perhaps as simple as having php create a file, and IDL look for the
file, and when it finds sees the file, IDL executes something).

Cheers,
bob
