PHP 7.2 Install

IMPORTANT: These instruction are only for a new server installation or those who wish to remove the previous version of PHP and run ONLY PHP 7.2 on the server.

If you are upgrading a server to PHP 7.2, and still need to be able to run a previous version of PHP, please see the PHP 7.2 Upgrade Instructions

Additionally, REDHAT 8 does not auto configure php-fpm as it does in previous versions, so for REDHAT 8, the upgrade instructions should be used: PHP 7.2 Upgrade

Note to Licensed Customers:

The following information represents the process we use to upgrade hosted installations.

The repos may vary depending the installation.
Licensed customers are welcome to use any repos they deem appropriate.
All modules listed under "Install the PHP modules required by PCR-360 " are required for PCR-360 to function correctly.
The only optional modules are the installation-specific modules listed below the required ones.
Zend Guard Loader is not supported in PHP 7.2, is not included in the required modules, and may be safely removed.
MCrypt has been deprecated in PHP 7.2, but is still available as an addon module.
In PCR-360 version 2019.1, we will be removing the usage of MCrypt in favor of OpenSSL encryption. For version 2018.1, MCrypt is still a required module.
