Hi Larry & Jonathon,
Thanks for the replies, much appreciated. Certainly there are comparable alternatives to authorize.net (Sage pay for one I believe) however I was wondering as much as anything if anybody had experience with some and any recommendations on them.
I'm sure like Jonathon said it should be simple enough to work through paypals documentations on web payments pro so I will likely look into that.
On a side note after this rewrite on php and mysql (i know that will hopefully contain a fair bit more mysql) and then your JavaScript book are there any plans on a new mysql book as I feel it's my weakest point but your last book is slightly out of date? I might be very wrong as I have not read it, but do you still feel it's relative to today's mysql or does your php & mysql book replace the mysql book? (I'm just going on publication date).
Thanks, keep up the great books as they make learning it all very enjoyable,
Alex
