DPC2019: PHP Opcode? What's that? - Benoit Jacquemont
"PHP Opcode? What's that? by Benoit Jacquemont
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.
What you'll learn from this talk:
how the Virtual Machine inside the Zend Engine works
how the PHP code is turned into opcode
how the opcode cache is used and how to check if it's efficient
what the optimizer part of the opcode cache is doing
