Question
Which PHP versions are supported in Plesk 17.8 for Linux?
Answer
In case of an upgrade from Plesk Onyx 17.5, all PHP versions supported in Plesk Onyx 17.5 are supported in Plesk Onyx 17.8.
However, in case of clean installation on new operating systems like Debian 9 or Ubuntu 18.04, it is not possible to install PHP 5.x and lower via Plesk Installer as this PHP versions are not compatible with newer OpenSSL version shipped with those operating systems.
Additional Information
Is it possible to install php 5.x in Plesk on Debian 9 and Ubuntu 18 via Plesk Installer?

Well it would be good to clearly state here, that it is also depending on the OS Version otherwise it is somehow missleading !
like the note in the Docu: https://docs.plesk.com/en-US/onyx/administrator-guide/web-hosting/php-management/installing-php.75153/
Note: On newer OSes (for example, Debian 9), older PHP versions (5.6 and earlier) may not be available for installation because they are not compatible with the modern OpenSSL versions those OSes ship with.

Hello, @Jürgen Fröhler.
That's a good point indeed.
I have updated the article making it clearer that on some OSes there is no way to install old PHP versions.
Thank you for the feedback!
