Question

Magento version 2.2.5 doesn't support php 7.1.x and Magento 2.3.0-beta12 requires php ~7.1.3||~7.2.0

Magento 2.1.x technology stack requirements

Magento 2.3.0-beta12 requires php ~7.1.3||~7.2.0

Now, what should i do if i want to run both Magento projects ?

Answer 1

Actually, Magento 2.2.5 runs perfectly fine on PHP 7.1.x. You should simply try it.

The general and larger question that you have is:

can I somehow run two different applications on two different php versions on the same server?

Well, yes, this is possible.
