Question
How to run PHP scripts on Plesk with different versions of PHP?
Answer
As it is possible to install multiple PHP versions via Plesk Installer, there is an option to work with all of them via the command line. All custom PHP handlers provided by Plesk are located in /opt/plesk/php/. Here are some examples on how to run and use it via SSH:
-

# /opt/plesk/php/5.6/bin/php -v
