Please note that the PHP version alone is not enough to know what
exactly you are using. For example, you could be using the Apache
mod_php module (Debian package "libapache2-mod-php5") or maybe PHP-FPM
(Debian package "php5-fpm").

Both are available in jessie and both are "PHP 5.6", but PHP-FPM is
usually much better.

BTW: Are you sure you are using jessie and PHP 7?
(There is no PHP 7 in jessie).
