Are the variables are in python, or in hscript? If they're in python, then
you just use normal python methods for getting your variable into a
string, and pass the complete string to hscript:

    object = "/obj/geoTest"
    command = "opparm -c %s cache_execute\n" % object

For more info on that, see:

If the variables are in hscript, then you can just use the exact same
command as you'd type into hscript:

    phpscript.write("set object = /obj/geoTest\n")
    phpscript.write("opparm -c $object cache_execute\n")

The "bye" command, I think, exits hscript (I don't have houdini in front of me
at the moment, so I can't check to be sure). Rather than using "bye", however,
I'd just close the pipe.

That email was written in 1999. No doubt, you're using a more recent version
of python. :)
