Thanks so much, Larry. That was a good explanation. I've been wanting to ask this question for a long time.
I must say that I consider you the best teacher around. I covet your books, and I have done things I never dreamed possible because of your excellent instruction. I am very eager to get my hand on the newly revised Effortless E-Commerce with PHP and MySQL.
Keep up the good work.
All my best to you,
Lori
