It's All About the Goto

Explore the inner workings of PHP in this in-depth conference talk from PHP UK Conference 2017. Delve into how different language keywords and constructs are handled internally, with a focus on the conversion to goto statements. Examine the various stages of PHP execution, including tokenization, parsing, and bytecode generation. Learn about complex language constructs like loops and exceptions, and how they are implemented at a low level. Gain insights into code analysis techniques such as branch analysis and code coverage. Ideal for developers seeking a deeper understanding of PHP's internal mechanisms, this presentation features detailed explanations, assembly-like code, and tree structures to illustrate key concepts.
