@mvorisek Would be great if CI is set up, I can only "build test" OCI.

For CI setup look into https://github.com/mlocati/docker-php-extension-installer/blob/master/install-php-extensions. It is quite easy with Debian. Do not try with Alpine, with Alpine, it is quite complicated.

I now realized PHP 8.3 has working CI - https://github.com/php/php-src/blob/PHP-8.3/.github/actions/setup-oracle/action.yml - it was only unbundled, so the CI should be copied from there.

And in the future, if package is unbundled from php-src, never without CI :)

I'm not going to set up CI here, but I see there's a separate WIP CI PR that stalled that could be used as a basis.

I agree
