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.
