I have so far avoided PHP in my career; Do I understand correctly that your template shows how to program Rust modules, that can then be called from PHP? Impressive!
That is a massively interesting strategy to get PHP-coders interested in more robust programming languages!
You are providing the " gateway drug to safety" for them.
P.S. I had to look up "THIMC" ("To whom it may concern"); acronyms aren't always clear, especially for non-native speakers, or across culture boundaries
