I am using php 7.2 but I can choose between (5.6, 7.0, 7.1, 7.2, 7.3, 7.4, 8.0).
I had great difficulty installing phpvms 7 mainly because I don't have great knowledge on the subject, so I chose version 5 for ease of installation. My idea is to create a virtual airline for pilots who play on xbox so only the function is needed of sending manual pireps.
