I found that in /var/www/conf/modules.example is a binary file named php-7.0.conf. I'm guessing that the content is the result of apxs2, not testing that binary anyways... Shouldn't be equal to the old file with the module extension configuration? I mean... text, not binary... I think there is a example in /usr/local/share/examples/php-7.0/php.conf
