How do I change the default PHP base-version on shell? – CentOS

I have Centos 7 and Virtualmin installed, with the tipycal php-fpm 5.4, 7.0, 7.1 that you can choice between the versions you prefer on every virtualhost via Virtualmin control panel, and everything works well.

But when I access to the server via SSH and check php -v I get this:

PHP 5.4.16 (cli) (built: Oct 30 2018 19:30:51)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies

How can I select another php default/base version for the shell system?

    When you issue the php command on the shell it uses the default php version on the server which in your case is php-5.4.16

    To use another php version, you have to check where the binaries for those php versions are and invoke them with their full path rather than just typing php.

    For example, on CentOS, for PHP 7.2 for example, the full path of the php binary is: /opt/rh/rh-php72/root/usr/bin/php

    root@virtualmin /root
» /opt/rh/rh-php72/root/usr/bin/php -v
