I don't know why passthru() wouldn't exist. Try adding a backslash before the call, like this:

\passthru($command);
That will guarantee that PHP will look for the root passthru().

I'm sorry. I don't know enough about php and running my own server to recognize this as the same problem with exec(); Hopefully this issue will help someone else.

The pdf generated is awesome!
