PHP needs updating

[pehdevx1]

Wordpress 5.1.1 requires that php be updated to a more current version:
Upon testing of some of the features in a theme I'm testing, I'm sure I caused some errors into the logs.....

From the wp-admin dashboard:

WordPress has detected that your site is running on an insecure version of PHP.

What is PHP and how does it affect my site?
PHP is the programming language we use to build and maintain WordPress. Newer versions of PHP are both faster and more secure, so updating will have a positive effect on your site’s performance.

According to the Health Check plugin:


PHP Version 5.5.38 - Your version of PHP, 5.5.38, is very outdated and no longer receiving security updates. You should contact your host for an upgrade, WordPress recommends using PHP version 7.2.

You can change your PHP version manually in your cPanel by clicking on Select PHP Version under the Software category. x10 should really change the default version, as the current default is very outdated and insecure.
