[CentOS] Cloud and php

I am looking at cloud software.  On Centos7-armv7hl, of course.

I was pointed to Nextcloud, but v11 CAN work with php 5.4 in Centos7, 
but recommends at least 5.5 for security updates and performance 
(important on arm), but recommends php 7.  Nextcloud 12 has a minimum 
requirement of php 5.6 (according to their install pages).

So.

What are others doing for:

Cloud

Php

???

I could always start with Fedora26, but want to stay with Centos if I can.

thank you.
