Don’t worry, this is not about the goto keyword. In this presentation, I am showing you some of the inner workings of PHP. We are going to look at how different language keywords and constructs are handled internally. Everything is converted to goto, but the how and why is not as simple as it seems! This in-depth talk will be of most interest to people who want to know how PHP works internally. Expect lots of wonkiness, a form of assembly, and trees.
