PHP for apps outside virtualmin? Zabbix and PHPMyAdmin shows code

Mainly trying to get Zabbix installed on my Debian 9 test server but when I fo to ip/zabbix I only see the <?php code
Trying PHPMyAdmin from debian apt-get so its installed globally on all sites as a test, shows the same thing.

What would I need to change to get Zabbix working on PHP.
PHPMyaAdmin was just a test as I know and do use it in virtualmin script installers.
Zabbix isn’t a script install.

Running Debian 9 and PHP 7.
