I saw the future, and its web servers were written in PHP
summary
Covers how PHP can move beyond CGI-style request/response by using PHP-based web servers and event-driven components such as ReactPHP, Icicle, Aerys and PHP-PM to keep frameworks (e.g. Symfony) running in a loop rather than restarting per request. Compares this approach to language-native servers like Jetty/Puma/Gunicorn, explains engine changes in PHP 7 (catchable fatal errors) that enable long-running PHP servers, and outlines performance gains and new capabilities (streaming request bodies, WebSocket upgrades) along with trade-offs required.
