What kind of PHP setup are you using?

Slide 4

Slide 4 text

Existing setups • Apache + mod_php • Apache + php-fpm • Nginx + php-fpm • Standalone PHP servers (ReactPHP, Swoole, RoadRunner) • FrankenPHP

Slide 5

Slide 5 text

Nginx • Event-driven architecture, handles thousands of concurrent requests e ff i ciently • Serves static fi les directly without passing requests to PHP • Load balancing and reverse proxy capabilities • Handles concurrent connections better than traditional web servers

Slide 6

Slide 6 text

php-fpm (FastCGI Process Manager) • Handles dynamic PHP requests separately from the web server • Uses process pools (static, dynamic, ondemmand) to e ff i ciently manage multiple requests • Provides better security by isolating PHP execution from the web server • Allows tuning of worker processes, memory limits, and timeouts for performance optimization • Communicates with Nginx via FastCGI protocol

Superpower - worker mode • Boot your application once • Keep it in memory • Process incoming requests without having to boot your application again • Relies on goroutines and channels • Symfony Runtime compatible • Some resemblance with RoadRunner
