PHP Class Help!

[Pound]

So I am trying to bulk edit domains in cPanel and apparently this does the trick. I have uploaded the script, however, the main problem is that I'm not sure which bits to edit! (at the moment I am getting "No input file specified"):

I was hoping someone could help tell me which parts I should edit to reflect my hosting!

Create domains.txt, ensure it's readable, add the data as described in the file. Run the script...

P.s. It's not classes, and it also doesn't seem like it can edit subdomains, it can only add them.
