The PHP Roundtable podcast, hosted by PHP community member Sammy K Powers, has posted their latest episode: Episode #64 - PHP 7 Source Code: A Deep Dive. In this show Sammy is joined by Sara Golemon, a core language contributor and XHP.

We take a deep-dive into the underlaying structure of the the PHP source code and talk about the scanner, parser, the new AST layer (and the evil things we can do with it), and the Zend engine. Let's see how the PHP sausage is made!
