PHP API Has HTML No Text Assets

When I use the PHP code I see it has no text assets but has an HTML asset. HTML has been deprecated, so what use is the software for creating videos?

I had the same problem reported elsewhere of truncated error messages. Why doesnt this work correctly when there is a perfectly good fix?

I get the feeling that this PHP software is given very little attention. Am I right? I’ve had to write my own (albeit with much fewer options).
