I am running a PHP based application on SLES 12 SP4. It uses ZipStream (https://github.com/maennchen/ZipStream-PHP). After one of the recent updates, I started having issues and it seems to be related to the PHP version. ZipStream site states that the minimum PHP version is now 7.1. My SLES 12 SP4 server is running PHP 7.0.7. Is it possible to get a newer version of PHP on SLES 12 SP4? Or do I need to upgrade the OS to something newer? Thanks!
