What version of the buildpack you are using? https://github.com/cloudfoundry/php-buildpack/tree/a4b4b1e8ed800dfa35ba2d3aa20a578208a558d1 (Develop) candidate for next release (v4.5.0)

If you were attempting to accomplish a task, what was it you were attempting to do?

1. Create a new user provided service with name caapm-test-something
2. Push (without start) the content of this fixture (using the Buildpack version pointing to develop changes)
3. Bind the service created with the app
4. Check the logs

What did you expect to happen? Deploy a new app with the CA APM Agent configured

What was the actual behavior? CA APM PHP Agent not supporting PHP 8>=
