and yes, I did sign up just to reply this message. But since I'm now a member, I think I will contribute something.

Great to have a new useful member!

That is what I meant with "PHP isn't the best language for this".

If you wanted the fsocket method instead of the curl you should've just said so
Anyway; I made you a little something. Happy x-mas!
It could be that you're only interested in the '//The actual shit' -part.
