Xdebug Ubuntu 18.04 and PHP 7.2

I just updated Ubuntu to version 18.04 and I have version 7.2 of PHP, if I execute the command “php -v” I get this result

root@laptop1:/etc/apache2/sites-enabled# php -v
PHP 7.2.3-1ubuntu1 (cli) (built: Mar 14 2018 22:03:58) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.2.3-1ubuntu1, Copyright (c) 1999-2018, by Zend Technologies
    with Xdebug v2.6.0, Copyright (c) 2002-2018, by Derick Rethans
root@laptop1:/etc/apache2/sites-enabled#

However, if I run the phpinfo() command inside a php file through a web browser I get the following: it tells me that I have version 7.1 of PHP and that I do not have the Xdebug activated.

For this reason Xdebug does not work with my PhpStorm IDE; I do not know if the best option is to delete all the PHP versions installed and leave one that is not as recent as 7.0 or 7.1.

There is a difference between what version of PHP you use in your terminal and what version your web-server (in example apache2) is using. If you have apache2, you can change the version of PHP to 7.2 with the following commands:

Dissable PHP 7.1:

sudo a2dismod php7.1

Enable PHP 7.2:

sudo a2enmod php7.2
sudo a2enmod proxy_fcgi setenvif
sudo a2enconf php7.2-fpm

After that restart apache2:

sudo service apache2 restart
