I was poking around in the available SCLo package tree and I noticed that rh-php71 is available, but not installable because there are no public packages to satisfy its dependencies:

http://mirror.centos.org/centos/7/sclo/x86_64/rh/rh-php71/

I poked around the buildlogs trees and found that it IS available there, last touched in August:

https://buildlogs.centos.org/centos/7/sclo/x86_64/rh/rh-php71/

Is there anything that's holding up php71 from reaching the release repo that I can help with?
