Elizabeth Naramore talks with David Soria Parra, Rasmus Lerdorf, and Stas Malyshev for a panel discussion about Internals. Our panel of experts will share their thoughts and predictions about the existing PHP landscape, and what is to come.

It's about 30 minutes long and they talk about PHP 5.4, compiling PHP, performance issues, the slow rate of adoption in newer releases, memory usage and some of the general strengths and weaknesses of the language. Elizabeth also asks each person on the panel about things they've each seen done wrong on the project and something they'd like to see in its future.
