Even wanted to contribute to PHP's Core? This is your time! From tests to a new function, PHP is open for new contributors. Fixing bugs, document things, cleanups, refactorings, or even new small functions. In this talk, we're gonna see how the `is_countable` function was made, and what we can learn from that.

Great introduction to how once can start contributing to the PHP core even without extensive knowledge in C. The speaker walked us trough getting an idea for a new function, implementing it (by getting inspiration from similar code) and getting it merged trough the RFC process.

One little nitpick he sometimes skipped from one thing to the other quite fast and I couldn't understand what exactly he was saying. However that's probably because we both aren't native English speakers.
