Hi Kévin, glad to see another controller library! This doesn't look to attempt much response parsing, nor has TorControl.php been touched for six months. I take it as if this is no longer under active development?
I'm hesitant to add this to the volunteer page since the purpose of that site is to direct volunteers toward active projects they can contribute to. That said, this would be a perfect fit for a stem FAQ entry on alternate controllers (there's quite a few small ones, including java and a shell script off the top of my head).
Cheers! -Damian
