Answer 1

I have two versions of PHP in opt/remi folder php56 and php72

how to set default version to PHP 7.2

SCL are designed for parallel installation so don't alter default version in base system

Once the collection is enabled, the version will be used

$ scl enable php72 bash
$ php -v
PHP 7.2.8 (cli) (built: Jul 17 2018 05:35:43) ( NTS )

If you want 7.2 to be the default version (base system) you should install it, according to Wizard instructions for "Default / single version" (and keep 5.6 as secondary version)
