PHP OpCode? What's that?

PHP OpCode? What's that?

Every PHP developer heard about OpCode, the magical sauce that runs inside the Zend PHP Engine in order to boost performances.

But what is exactly that OpCode? Why does it make the Zend Engine faster to run your PHP Code? Is it only about performances?

The aim of this talk is to demystify what's going on inside the Zend PHP Engine and to understand what is happening to our PHP code when it's digested by the interpreter and turned into opcode, before being executed on the Zend Virtual Machine.
