What even is PHP?

On this episode hosted by Jennifer Blumberg with guest Matthias Noback, we continue the “What is even…?” series by delving into exactly what even is PHP?

We talk about PHP’s originals, how PHP works from request to php-fpm worker processes to lexer to bytecode to JIT, the whole shebang!

We also discuss there are so few feature-rich, authoring experience focused CMSs written in languages other than PHP.

Finally, we talk about Rector, which is like Babel but for PHP, allowing you to improve and upgrade PHP code on the fly. It can even downgrade your code to older PHP versions if you like!
