Use go:embed embed.FS rather than tar + exporting files to a temp directory?

I've made this a discussion rather than issue, as I'm not sure if it is valid or not.

I was just exploring how FrankenPHP does the embedded builds, and it looks like

1. you set an env variable with the path of your application then run the build-static.sh script which creates a tar of the application which gets embedded
2. when the binary is run, the tar gets extracted to a temp directory

I wonder if the whole process could be simplified if you use the embed.FS which "implements fs.FS, so it can be used with any package that understands file system interfaces, including net/http, text/template, and html/template."?

Moreover, it might even be higher performance since the files would be read from within the binary rather than the temp directory. Furthermore, I could see this being useful in the sense of wanting to protect Intellectual Property by not extracting php files. I dont know if this would result in extra/excessive ram usage though, as compared to the tar extraction.

I also wonder if it could perhaps even somehow be pre-compiled into the opcache?

This would need support in PHP itself (particularly the require/include/require_once/include_once directives) as well as a custom stream filter to intercept local files -- it would be similar to the phar implementation, just with go-specific access.

ah ok, i didnt think of how php itself needs to use the filesystem. Surely not worth the effort to implement something like this. Thanks!

Hi, i just stumbled across this whilst checking if FrankenPHP supports the Caddy builtin filesystem directives: it seems like not currenty based on the response.
Hypothetically if i would implement something like win32/ioutil.c (in php source) as a patch but for a go backend would that support the bulk of file io operations right? or do i need to patch other places too?

if this work one could use such cursed caddy filesystem backends as https://github.com/mohammed90/caddy-git-fs for serving php
