PHP 7.1 support

[allyraza]

are there plans to support php7.1 with compiled artifacts? I have tried to use the provided artifact which is pre-compiled but that does not work for 7.1. I am currently trying to compile it form source to run it on ubuntu for some reason the compilation does not even complete.

I am looking into php 7.2 at the moment. 7.1 seems already out of date by now.
