Not you Rob, don't be so paranoid ;) I was just saying it for Govinda's benefit, as it seems to be particular to the system he is using, and I just thought I'd point out a couple of the more obvious problems with it.

Re: [PHP] logic for grabbing what we need from user-input addresses for AVS?
AVS generally only exists for us and canada and parts of the uk, if I remember correctly. Usually they're just looking for the beginning part of the street address, not the concatenation or anything else like that. No need for apartment numbers, for example if you're just looking at avs. If you're doing a full credit card auth, though, that's a different matter.
