Difference between PHP

I would like know which the difference between:
PHP 5.5, PHP 5.6 or PHP 7.2

If i have a linode with CentOS 7 if i install yum install php
by default come with version 5.4.

Some CMS say Install With Version Php 5.6 others say Php 7.2

The primary difference between different versions of PHP are the supported features. For example, the MySQL extension is deprecated in PHP 5.5+ and developers are urged to use MySQLi.

You can find more information on the deprecated features in the versions you mentioned on the following URLs:

You'll likely need a matching PHP version before installed scripts will function correctly.
