4. FrankenPHP A modern app server for PHP and Symfony ➔ Built for containers ➔ Worker mode ➔ 103 Early Hints support ➔ Real-time support (Mercure module) ➔ Compatible with all existing PHP apps: progressive enhancement
5. Symfony and Containers
6. Containers: Which SAPI? Server Application Programming Interface: interface between the PHP interpreter and web servers ➔ Apache module ➔ FPM (FastCGI Process Manager) ➔ CGI (Common Gateway Interface) ➔ NGINX Unit (not the NGINX you’re used to) ➔ …
7. ➔ Simple ➔ Web server + PHP = 1 service ➔ Default solution for containers DRAWBACKS: ➔ Works only with Apache ➔ Less performant than FPM Apache Module
8. FPM ➔ Most popular SAPI ➔ Supported by most web servers: Caddy, NGINX, Apache… DRAWBACKS: ➔ External service ➔ Require a UNIX or a TCP socket ➔ Hard to containerize

10. Can We Do Better?!
11. ➔ Perfect for containers ◆ Just 1 service ◆ No external dependencies ◆ Batteries included ➔ Contains the Caddy web server ◆ All Caddy features and modules ◆ Benefits from Go features ◆ Extensible: in Go, in C, in PHP ➔ Prod, CI and dev FrankenPHP: Modern PHP App Server
12. ➔ Standalone Go library ➔ Embed PHP in your Go programs ➔ New SAPI for Go net/http ◆ Caddy, Symfony CLI, Traefik, K8S… ◆ Your custom Go app ➔ Caddy module using the library ➔ Unique features The ❤ of FrankenPHP: A New SAPI For Go
13. ➔ Easy to configure ➔ Cloud native: API, hot config reloading… ➔ Automatic HTTPS ➔ HTTP/2, HTTP/3, Early Hints… ➔ Extensible with modules: Mercure, Vulcain, OAuth, OIDC… ➔ Prod ready ➔ Server of Symfony Docker ➔ Written in Go 😻: secure and fast Caddy: The New Kid on the Block
14. ➔ Compatible with existing PHP apps! ➔ 1 service, 1 minimal Docker image 😍 ➔ Also works without Docker ➔ Entirely configurable ◆ Caddyfile ◆ php.ini ➔ Free software (as in free speech ✊, and free beer 🍺) FrankenPHP: At a Glance
15. Getting Started
16. Getting Started
17. Alternative: Symfony CLI ➔ Simple local web server ➔ Built-in TLS support ➔ Dev environments only ➔ Auto-detects and auto-configures: • PHP FPM and CLI • Docker Compose services: Postgres, MySQL, Mailcatcher, Redis, RabbitMQ… ➔ Works with any PHP app (even if not using SF) ➔ Written in Go 😻 @dunglas
18. 🧪 Symfony CLI X FrankenPHP
19. FrankenPHP Superpower: The Worker Mode ➔ Boot your application once ➔ Keep it in memory ➔ Process incoming requests without having to boot your app again ➔ Relies on goroutines and channels ➔ Compatible with Symfony Runtime ➔ Somewhat similar to RoadRunner ➔ Unlike RoadRunner ◆ runs in process: no network calls, no gRPC ◆ uses plain old superglobals: no PSR-7
20. Worker Script
21. Starting the Worker Mode By default, one worker per CPU is started.
22. The Runtime Component
23. Symfony App in Worker Mode
24. FrankenPHP: Worker Benchmark 🧪 ➔ Setup: ◆ Hello World Symfony app (prod mode) ◆ Caddy Web Server (HTTP/2) ◆ 3000 requests, 100 connected users ◆ Benchmark tool: K6 ➔ Average request duration: ◆ FPM: 9.45ms ◆ FrankenPHP (worker): 2.53ms ➔ Take it with a grain of salt, run your own!
