I have a problem with installing Phalcon for PHP 7.1
There is a VPS with ISP Manager Lite 5 control panel in which a PHP selector is built.
The main version of PHP on server 5.6 and Phalcon compiled and works well with it.
For individual domains, I choose PHP and Phalcon 7.1 of course for this version Phalcon is not installed.
How can I install Phalcon in this case?
