PHP UK Conference 2016 - Juozas Kaziukėnas - From PHP to Machine Code

This talk explores the inner workings of PHP execution, specifically focusing on what happens when a command like `php example.com` is run. The speaker shares insights gained from building a PHP interpreter, explaining concepts such as opcodes and bytecode cache. With the existence of two main alternatives, standard PHP and Facebook's HHVM, the session delves into the complexity of these projects and emphasizes the importance of understanding programming language principles rather than relying on them to function properly.
