What is PHP?
Let’s geek out a little bit here, if you don’t mind. For those who don’t know, PHP is a programming language that popular web platforms/CMS’ are written in, WordPress and Drupal for example are written in PHP.
PHP is an open source language and like most software is updated and modified over time. These modifications include performance improvements, new features, bug fixes and security patches. The PHP Group maintains the software and publishes these updates at php.net.
The software developer writes for compatibility with the version that is installed on the host server.
As software developers we write in our chosen language, such as PHP, to be compatible with the particular version we plan to deploy it on. However over the years different versions are retired so that focus can be maintained on the latest and greatest versions.
The PHP group maintains several versions in various stages of lifecycle. These go from Initial Release to Active Support and then Security Support. Each phase is given a particular amount of time until it has expired. Meaning with each version of the platform we know that it will be supported until a certain date. The most important phase here is the Security Support, which once it ends, it basically means that all support for that particular version has stopped and most importantly, no more security patches will be released. At this point it is important that your web application be updated and moved to a supported version of the language.
What This Means for FatLab
From a hosting perspective FatLab has supported sites/applications built for PHP versions 5.3.x, 5.6.x, and 7.x. The current/latest version is version 7.1 (there was no version 6 released). As of this blog post our support policies and upgrade roadmap is as follows:

So Why Do We Have to Upgrade?
SECURITY! The number one threat to any system is outdated software and software that is no longer receiving security updates should be considered a major risk.
How Hard is it to Upgrade?
Let’s talk about WordPress since 99% of the sites we host are WordPress based sites. For most WordPress sites, the upgrade is fairly easy as the majority of WordPress software is PHP 7 compatible. It’s only sites that use plugins or themes that have php code that is no longer supported by the latest version, or sites that are unable to upgrade their WordPress core because of one reason or another that may pose challenges. Sites that we typically see issues with are those with custom applications developed for them (i.e. not using standard plugins) or sites that use older themes. It depends on the scope of incompatibility that determines how big a challenge an upgrade might be.
Our Upgrade Strategy
For all the sites we host we will take care of the testing and migration with zero down time. For those sites that prove to be incompatible we will contact the individual client to discuss options. For those sites we do not host but maintain, we will advise our clients if they are on an unsupported version and work with them to develop an upgrade plan.
