I am running a cpanel apache mysql configuration. Under the latest cpanel you can run PHP per site, so you could set this in your control panel and run PHP 7 on your site. In my case, I wanted it to run within a directory, so I added this to the root .htaccess file for my Revivie Adserver site:
<IfModule mime_module> AddType application/x-httpd-ea-php70 .php .php7 .phtml </IfModule>
I then edited the main configuration file from:
[database]
type=mysql
