Cant change PHP version above 7.0

I’m installing an index page for my website from a website called gmodstore (You would know what it is if you host a gmod server) and it requires PHP 7.2 which the panel does not have. How do i get php 7.2?

You’ll get PHP 7.2 soon. We don’t have PHP 7.1 or 7.2 yet, but they will be added in the near future.
