Aaron will be presenting at Zend PHP/Conference and Expo this year so I thought it would be fun to talk to him a bit about his presentations. So I called him. Luckily for me, I did this early in the morning CST so I caught him just after his afternoon nap.
They quickly talk about Aaron's talk ("Moving to PHP5 With Style"), what to expect from it, why anyone would want to make the move from PHP4 to PHP5, and his favorite feature og PHP5. But you'll just have to read the interview to find that one out.
