PHP 5 and PHP 7 after UBUNTU update to 16.04?

Question

linux

Good afternoon. Updated Ubuntu to 16.04. Now I don’t understand something: it appeared in addition to php5.6 - php7 and if I put some extension, then it doesn’t appear in the /etc/php5/mods-available ini directory, php -m does not show this module (for example, php -gd), but it appears in /etc/php/7.0/mods-available.

which php = /usr/bin/php
ls -la /etc/alternatives/php = /etc/alternatives/php -> /usr/bin/php5

update-alternatives --display php
php - auto mode
  link best version is /usr/bin/php5
  link currently points to /usr/bin/php5
  link php is /usr/bin/php
  slave php.1.gz is /usr/share/man/man1/php.1.gz
/usr/bin/php5 - priority 50
  slave php.1.gz: /usr/share/man/man1/php5.1.gz

dpkg -l | grep php-gd
ii  php-gd        1:7.0+35ubuntu6     all   GD module for PHP [default]

And, when you put some extension, you can see that it is enabled only for php7:

Accordingly, php -m does not display information about the sqlite3 module. But, if I display the result of the phpinfo() function in the browser through mod-apache, sqlite3 is loaded there.
What's wrong with me?

In Debian PHP 7.0 put in /etc/php/
