Command-line arguments (Server)

After a good few weeks of (many) attempts, i've filnlay got upto this tut without any errors! Thanks for doing them, literally the best series of php tutorials i've come across although at first I cursed at not having a copy of finished source code to compare it too, now that i've gone through all the bugs i accidentally created (and was able to understand why they were bugs!) myself, I feel like i've learnt *a lot* more than if I just copied the correct section from a finished source. Thanks!
