To be sure not to have problems, do not exceed the php 7.0xxx version on the development, and most importantly, keep the php version 7.0 on the production, because I made the bad experience of many mistakes, one. com forced me every half hour in 7.2 (while my site is in full production, (school site with encoding points, etc.)), I went to scriptcase.net (OVH), at least we can manage php versions , some like one.com force to upgrade to version 7.1 or 7.2 while nothing is stable in the last two versions, this is for experience, not as advice, everyone makes his choice.
