Thank you, unfortunately it's the server at work and seems to be quite locked down, any of the files that phpDocumentator tried to write wouldn't work, and any time it tried to connect to the internet the firewall blocked it.
I can see if I can install xampp (again, the computers at work are quite fussy) and copy the code across, that's actually a neat idea, thank you - I think ideally I was hoping for something I could install on my machine (without the need for services, registry changes etc) which could then scan the folders on the server for the files
