Hey Michael,

It's not entirely clear to me what you're asking for here. Is it about
producing actual build artifacts? It's not possible to produce useful build
artifacts for PHP, because the number of dynamically linked libraries will
make them non-portable. The only thing we could produce are Docker images
-- and other people already provide that service.

If what you want is to just determine whether a certain commit is a good
base for a nightly build, I'd suggest finding our how to query scheduled
builds on Azure pipelines (builds like these:
https://dev.azure.com/phpazuredevops/PHP/_build/results?buildId=3D13228&vie=
w=3Dresults)
and check whether they pass. Note though that these will commonly fail even
on good commits, because they run tests in more than 60 different
configurations, and as such spurious failures are common.

Nikita
