Upgrading mod_php with Apache
This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.
Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.
sudo yum remove php-cli mod_php php-common
Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.
sudo yum install mod_php70u php70u-cli php70u-mysqlnd

sudo apachectl restart

systemctl status httpd
