PHP UK Conference 2018 - Derick Rethans - Introduction to PHP Extensions

This talk provides an introduction to writing PHP extensions, showcasing the process through step-by-step examples. The speaker demonstrates how to convert a function written in PHP into a loadable extension using C, followed by testing both versions to compare outcomes. Attendees will learn the significant advantages that can be achieved with minimal changes and gain insights into the importance of starting with simple implementations rather than attempting to rewrite entire frameworks like Symfony in C.
