The x86 extensions for Apache and PHP have been aligned to match the x86_64 extensions. The extension you need to get the same as before is php7-mod (and its dependencies) and whatever TC extensions you need to support the PHP extensions you use. Now you have the option of using FPM instead of the Apache mod, though you still can if you want, and you can use Nginx (with FPM) instead of Apache. Personally, I would recommend you give PHP-FPM and Nginx a try. A lot less resources, meaning lighter and faster.
