You don’t update PHP in a container. You download a new image with a new PHP version. If you use a wordpress Docker image, you can download a new version of that. If you can’t find a new wordpress image with a new PHP version, because that wordpress is not supported anymore, then you need to build your own Docker image and recreate the container…
