We could use https://github.com/nbd-wtf/nostr-tools/blob/master/nip19.test.ts as starting point. Converting the tests to php and then implementing the code.

That's one of the reference I was looking at too, combined with the go-nostr library
Excellent, I am working on an implementation, but it is challenging me. I translated the tests to php, but I think I am now at the part where I need to convert the data to bits. Will continue monday, but hopefully sooner. How is your progression?
You can check my latest commits in the nip19 branch in the nostr-php
