Upgrade CentOS PHP 5.4 to 7.3 on CentOS 7

CentOS 7 comes out with PHP 5.4 by default, this is quite old by today's standards and a lot of the inbuilt functions are missing. The following instructions will upgrade PHP from version 5.4 to 7.3

Confirm you have PHP 5.4 installed on the server

php --version
