This is more of a request than a support question, let me know if i have to make this request somewhere else.
GRPC and protobuf are required to run temporal with php. As of now there is no php docker image that comes with a prebuilt grpc and protobuf modules installed. The issue is that installing grpc from pecl takes 20-30 minutes, unless cached strategically or using a multi stage builds.
Temporal team can host a php docker image which comes with these prebuilt it will make a world of difference in developer experience.
This issue has been highlighted and people have found their own way around it ( https://github.com/grpc/grpc/issues/34278 )but it would be great if there an official source which will be maintained for this.
