Features

Prometheus metrics

The server exposes Prometheus metrics on /metrics endpoint. You can set up your own endpoint by setting X-App-Route header in your PHP application (header is not propagated to client).

Using UNIX socket

The fastest way to communicate with PHP-FPM is to use UNIX socket. You can set up your PHP-FPM process and then pass socket path to the web server. For docker-compose you can use a mount volume to share socket between containers. In Kubernetes you can you EmptyDir volume.

PHP-FPM config

[global]
daemonize = no
[www]
listen = /sock/php-fpm.sock
listen.mode = 0666

Static files

Server can serve static content. It's recommended to use different approach for serving static files, but if you need, gophpfmp is ready. You can set up multiple static folders. Each folder is mapped to a different endpoint. For example /static endpoint can be mapped to /home/app/static folder. For more info see --static-folder flag.

Security

There is no way how to call other scripts. It's always a PHP file specified in configuration. It's suitable for modern PHP frameworks like Symfony. No .htaccess, no routing.
