Hey @musdev,

UPDATE: PHP 8.2 is now available and the docs have been updated:

https://docs.digitalocean.com/products/functions/reference/runtimes/php/

Indeed PHP 8.2 is not yet available on the App Platform. The latest PHP version available is 8.1.18 as of the time of writing this post.

The best thing to do to get your voice heard regarding this would be to head over to our Product Ideas board and post a new idea, including as much information as possible for what you’d like to see implemented.
