Update: I will no longer be posting articles here. Instead, checkout the PHPInternals.net website for new content around PHP's internals.
PHP Internals Articles
This repository contains articles that will aim to provide an introduction into PHP's internals. Some articles will take a pragmatic approach (typically having more breadth with less depth), and other articles will focus solely on particular aspects of internals (typically having less breadth with great depth). All of the articles here will be written for PHP 7 (powered by the Zend Engine version 3 (ZE3)) and above.

- Implementing a Digit Separator in PHP
Feel free to open up issues to request/suggest topics that you would like to see covered!
