Hi @donhardman

I've added yaml for github actions (we were previously using travis ci). Can you please add php 8.1 to the matrix (https://github.com/manticoresoftware/manticoresearch-php/blob/master/.github/workflows/ci.yml#L17) and make sure your change passes the tests in the new version?

@sanikolaev Одобрите, пожалуйста. Нехорошо, что в логи постоянно валятся предупреждения.

@Fot0n asked to approve the PR. The problem is that we are waiting for a little improvement in the tests, but we can do it ourselves. Thanks for pushing this @Fot0n!
