Custom PHP (ini) settings in Caddy configuration

[ruudk]

I'm wondering if it would be possible to have custom PHP ini settings in the Caddy config.

I checked https://github.com/dunglas/frankenphp/blob/main/docs/config.md but couldn't find it.

Let's say you have 2 apps:

app.example.com {
    root /path/to/app/public/
}

other.example.com {
    root /path/to/other/public/
}

For other.example.com I want to define some custom PHP ini settings.

I would like to enable a PHP extension only for one host/app.

Having a possibility to define a custom / additional php.ini file, would also be great.

The use case that I want to explore is to load the Xdebug extension, once when the XDEBUG_TRIGGER query parameter is present. This way, you'll get a blazingly fast development server, and can trigger Xdebug (which slows down the request) on demand.

It seems that Nginx Unit supports custom PHP ini settings per app, so I think it should be possible.

I think this is better served in an issue, as it's more or like a feature request: #252
